- "Take Photos" Custom Setting
- "Take Photos" is a custom setting that allows you to capture still images while you are in the middle of shooting HD Video with select Nikon D-SLR cameras. Still images taken with the Take Photos feature will have a 16:9 aspect ratio, just like the video footage, regardless of whether the camera is set to FX or DX Crop.
- 1 NIKKOR
- The trade name given to the NIKKOR lenses that have been designed for optimal use with the CX-format Nikon 1 digital camera system.
- 14 Bit A/D Conversion
- Analog to Digital conversion is usually the first stage in the process of converting an analog signal coming from the image sensor via multiple channels into digital data for the image processing and storage of image data. The higher the bit rate of this conversion, the higher the image quality. Nikon D-SLRs typically offer a 16 bit image processing pipeline, which converts images of 12 bit or 14 bit depth quickly and efficiently.
- 153 Focus Point System
- Select Nikon DSLRs such as the D5 and D500 feature a system of 153 focus points, which broadly cover the image area at a high density for more accurate acquisition of subjects; 55 of which are selectable focus points. There are 99* cross sensors, of which 35* are user selectable (*depending upon the lens being used). Compatibility with f/8—15 focus points (9 are selective and the center 5 are cross sensors).
- 256-bit Encryption
- 256 bit Encryption is a security protocol that is characterized by key sizes that may be any multiple of 32 bits, both with a minimum of 128 and a maximum of 256 bits. This is a secure and very fast encryption type for both software and computers.
- 3D Colour Matrix Metering II
- Matrix metering evaluates multiple segments of a scene to determine the best exposure by essentially splitting the scene into sections, evaluating either 420-segments or 1,005 segments, depending on the Nikon DSLR in use. The 3D Colour Matrix Meter II takes into account the scene's contrast and brightness, the subject's distance (via a D- or G-type NIKKOR lens), the colour of the subject within the scene and RGB colour values in every section of the scene. 3D Colour Matrix Metering II also uses special exposure-evaluation algorithms, optimized for digital imaging, that detect highlight areas. The meter then accesses a database of over 30,000 actual images to determine the best exposure for the scene. Once the camera receives the scene data, its powerful microcomputer and the database work together to provide the finest automatic exposure control available.
- 3D Focus Tracking
- An invaluable feature for sports, action and wildlife photography, 3D focus tracking, available in select Nikon D-SLRs, automatically shifts the focus point to follow the movement of the subject. With the shutter release pressed halfway, you'll see in the viewfinder the lens continuously maintain focus as the subject moves.<br /><br />However, maintaining focus doesn't guarantee a sharp image, as there is a short time lag between the release of the shutter and the capture of the picture. To solve this problem, the focus tracking system is a predictive system that uses special algorithms to forecast the position of the subject at the moment the image is captured. The prediction is based on a measurement of the subject's movement and speed.<br /><br />Simple predictive tracking is very effective for pictures of a subject moving at constant speed toward the camera, but to provide maximum focusing performance for a subject that abruptly changes direction at high speed, or a subject with low contrast, moving randomly, the AF system must accumulate subject location data using multiple focus areas. The AF modules built into selected Nikon D-SLRs have as many as 51 focus areas that can detect vertical, horizontal and diagonal movement of the subject.<br /><br />To realize high-precision AF for high-speed continuous shooting of a fast-moving subject, the processing speed of the AF cycle is vital. To provide that speed, a Nikon proprietary technology called overlap servo prepares for the focus detection of the next shot while the lens-driving operation for the current shot is in process.
- 3D Matrix Metering
- An exclusive Nikon feature, Matrix metering applies three types of data to calculate exposure: scene brightness, scene contrast and the focused subject’s distance (which requires the use of a D-type NIKKOR lens).
- 3D Mode
Select Nikon COOLPIX digital cameras offers a 3D mode, which in effect takes two images that are played back on a 3D compatible TV or monitor for stereoscopic viewing.- 3D Multi-Sensor Balanced Fill-flash
- An automatic, balanced fill-flash system in which the flash fires a series of pre-flashes just before the first shutter curtain moves.
- 3D Playback Mode
- Only 3D images can be viewed in the 3D Playback Mode. It can only be chosen when the 3D-capable Nikon COOLPIX digital camera is connected to a 3D compatible TV or monitor via an HDMI cable.
- 3D Tracking (11-points) AF-Area Mode
- The 3D-tracking AF-Area Mode is an AF-Area Mode that is available in select Nikon digital cameras. When the user is in either AF-A or AF-C focus modes, the user selects the focus point. As long as the shutter button is kept pressed halfway, if the subject moves after the camera has focused, the camera uses 3D-tracking to select a new focus point and keep the focus locked on the original subject. If the subject leaves the viewfinder, remove your finger from the shutter release button and recompose the photograph with the subject in the selected focus point.
- 4 Second Movie
- A movie option that is available in select cameras such as the Nikon 1 V3. Record a 4-second movie clip. Multiple clips can be joined into a single movie using the Combine 4-second movies option in the playback menu.
- 4K
- 4K is an emerging standard for digital motion picture resolution. The standard is so named because it refers to its approx. 4,000 pixels of horizontal resolution. 4K incorporates a number of aspect ratios that all utilize 4,000 pixels of horizontal resolution x differing numbers of pixels of vertical resolution. This is contrary to the standard HD resolutions of 720p and 1080p which represent the number of vertical pixels.
- 51 Point Autofocus System
- Available in selected Nikon D-SLRs, the 51-point AF system positions 51 points of focus within the frame to allow photographers to choose a variety of focus configurations to suit the shooting situation.<br /><br />The 51-area grid forms a wide rectangle across the frame, with minimal spacing between each AF area. The system keeps even quick-moving subjects in focus across a wide extent of the frame. The 15 points of the three center rows of focus points employ cross-type sensors for powerful focus detection.
- 91,000 pixel RGB 3D Matrix Metering III
- Face detection using the optical viewfinder and detailed scene analysis using the 91,000 pixel RGB 3D Matrix Metering III sensor with the advanced scene recognition system enables superior auto exposure, auto white balance detection, AF performance and i-TTL flash exposure.
- A (Non-TTL Auto mode on Nikon Speedlights)
- The flash uses its sensor to measure the flash illumination reflected back from the subject controlling flash output to give correct exposure.
- A-M
A-M stands for Auto-Manual Mode.- A.GPS
- An Assist GPS (A.GPS) file is an updated file of GPS data that can be downloaded from the web and uploaded into select Nikon digital cameras to shorten the time needed by the camera to track the GPS positioning information. The website housing the A.GPS file is http://nikonimglib.com/agps/index.html. Once you download the file to your computer, follow the instructions in your camera's manual.
- A/M
A/M stands for Auto-Priority Manual Mode. This mode also enables an easy transition from autofocus to manual during AF operation. However, mode switch sensitivity has been altered to reduce the possibility of sudden unintentional switching to manual focus while shooting.- A/V Out
- Refers to a connection port for output of audio and video from a Nikon camera to a television using RCA plugs (composite yellow for video with mono white or stereo white and red for audio).
- AA (Auto Aperture mode on Nikon Speedlights)
- The flash uses its sensor to control the flash output in combination with data automatically transmitted from the camera and lens to the flash including the ISO sensitivity, aperture, focal length and exposure compensation value.
- AAC
- AAC is a standard audio file format. Nikon cameras record audio to the AAC monaural file format.
- ADL Bracketing
- Bracketing automatically varies a given set of variables dependent upon which type of bracketing is chosen. Use bracketing in situations where it may be difficult to set exposure or to experiment with different settings for the same subject. ADL Bracketing is Active D-Lighting Bracketing and when chosen it takes one photo with Active D-Lighting off and another one at the current Active D-Lighting setting.
- AE Bracketing
- Bracketing automatically varies a given set of variables dependent upon which type of bracketing is chosen. Use bracketing in situations where it may be difficult to set exposure or to experiment with different settings for the same subject. AE Bracketing will bracket the exposure over a series of three photographs. The first shot is unmodified, the second shot has a reduced exposure and the third shot has the exposure increased.
- AE Lock
- AE lock is used to hold an automatically selected shutter speed and/or aperture.
- AES Encryption
- AES stands for Advanced Encryption Standard. This is the preferred standard that is used to encrypt commercial and government data.
- AF Area Modes
- Nikon's three AF Area Modes—Single Point AF, Dynamic Area AF and Auto Area AF—are designed to handle any shooting situation.<br /><br />With good light control and a static subject, Single Point AF ensures that the most important element in the composition, such as the eyes in a portrait, will be sharply focused.<br /><br />With Dynamic Area AF, you can select from several focusing options: 9-, 21- or all 51-point AF. Select a Single AF point and the areas surrounding it serve as backup—a significant advantage when shooting moving subjects. Select the 9-point option when you want to focus on erratically moving subjects with greater accuracy. When dealing with insufficient contrast for fast focus detection, choosing 21 or 51 points makes detection easier. The 51-point option also allows for 3D Focus Tracking, which uses color information from the RGB metering sensor to automatically follow moving subjects across the AF points.<br /><br />Auto Area AF uses color information and special face recognition algorithms to automatically focus on an individual's face, which is extremely helpful when there's simply no time to select a focus point, or when using Live View in hand-held mode at high or low angles.
- AF Assist Illuminator
- A beam of light automatically activated to provide the camera's autofocus system the necessary light to operate in poorly lit situations. The AF assist illuminator's light does not appear in the picture.
- AF Lock
- Autofocus lock is typically used to hold focus on the part of the scene that's most important to you.
- AF Sensor
- The AF sensor is a sensor used to detect focus.
- AF Servo
- Essentially, motor-driven autofocus; engage it and a digital SLR's autofocus system will continuously track (focus) on a moving subject.
- AF-I NIKKOR Lens
- A NIKKOR lens with a built-in conventional rotor type autofocus drive motor.
- AF-S: Autofocus Silent
- Focusing is driven by a "Silent Wave" motor in the lens instead of the focus drive motor in the camera. AF-S lenses focus faster than standard AF-NIKKORs and almost completely silently. AF-S lenses with a "II" designation weigh less and are generally smaller than their equivalent predecessors.
- AI (Automatic Maximum Aperture Indexing) System
- AI became standard on Nikon cameras and NIKKOR lenses in 1977. Non-AI lenses coupled to the camera's meter through a system that required a pin on the camera to be mated to a slotted prong on the lens before the lens was mounted, then the aperture ring on the lens had to be turned from one extreme to the other to index the meter to the maximum aperture of the lens. AI eliminates this entire procedure because meter coupling and indexing occur automatically when the lens is mounted on the camera. Most AI lenses made until a few years ago were also supplied with the coupling prong so they would be compatible with either metering system.
- AI-P
- A manual-focus NIKKOR lens with a built-in CPU which transfers data from the lens to the camera's metering systems.
- AI-S: Automatic Indexing (modified)
- AI-S coupling is a refinement of AI and became standard on NIKKOR lenses in 1982. The diaphragm action in an AI-S lens is compatible with Nikon cameras that allow the aperture to be controlled from the camera, as is required for programmed and shutter-priority automatic exposure control. All AF-NIKKOR lenses, as well as most manual-focus NIKKOR lenses made since 1982, are AI-S. <br />
- APS-C
- APS-C stands for Advanced Photo System-type C, which is an image sensor format that is equivalent to approximately the size of the Advanced Photo System negative (25.1x16.7mm). The Nikon DX format image sensor is an APS-C format sensor.
- ARNEO Coat
An anti-reflective coating developed by Nikon and used in conjunction with Nano Crystal Coat to further reduce ghost and flare effects caused by incident light entering the lens vertically. This allows for the outstandingly clear capture of images even when a light source is located within the frame.- AS
AS stands for Aspherical lens elements. This type of lens utilizes non-spherical surfaces on either one or both sides of the glass in order to eliminate certain types of lens aberration.- ASA
- Measure of a film's "light gathering" capability. Replaced by ISO for film and digital.
- AVC/H.264 (AVCHD)
- Advanced Video Coding is a standard for video compression.
- AVI
- AVI Stands for Audio Video Interleave, a multimedia format used to record video.
- Aberration
- An aberration prevents light from being brought into sharp focus. The ideal image by lenses (especially photographic lenses), must fulfill three key conditions, namely, 1. all light from the point object must be focused to a single point on the image plane (film or digital sensor); 2. when the object plane is perpendicular to the optical axis, the image plane must also be perpendicular; and 3. the object and the image (on the film or imaging sensor) must closely resemble each other. In reality, however, light refraction by the lens causes a variety of defects in the image, called aberration.<br /><br />The five most common types in aberration are SEIDEL's five aberrations, which occur even with monochromatic (single-wavelength) light. In addition, there are also two types of chromatic aberrations, which are caused by more than one frequency. It is impossible to eliminate them all, but in the lens design process, they can be controlled and balanced to provide the best possible result for that lens and application. This is handled by material (glass) selection, shape and positioning.
- Action Control
- A mode incorporated into select cameras such as the Nikon COOLPIX AW100 and AW110 digital cameras and the Nikon 1 AW1. When the action control is set to ON, you can control certain functions of the camera simply by swinging it in the air. The default setting is HIGH, which means that even if the camera is shaken by a small amount, it will register. When set to LOW, a large amount of movement is needed to register by the camera.
- Active D-Lighting
- Active D-Lighting optimizes high contrast images to restore the shadow and highlight details that are often lost when strong lighting increases the contrast between bright and dark areas of an image. It can be set to operate automatically or manually, and it's also possible to bracket pictures to get one with Active D-Lighting and one without.<br /><br />Active D-Lighting's image optimization, which takes place in the camera at the moment the photo is taken, applies digital processing only to the necessary portion(s) of the image. Even when shooting a subject with a wide dynamic range, Active D-Lighting is able to reproduce a realistic image that retains natural contrast.
- Add Highlight Tag
- The KeyMission 170 action camera incorporates an Add Highlight Tag feature, which allows you to tag certain sections of your video by pressing the function button on the remote control during movie playback. This feature is the default setting of the Function button on the camera’s remote control. You can then select Create movie digest, in which the camera automatically combines the tag-attached sections (2.5 seconds before and after each tag) and saves the it together as a separate movie with sound.
- Add Slow Motion
- This is a feature of select cameras such as the KeyMission 170 action camera, which allow you to add slow motion to a portion of your video capture, as its being recorded. This is done by assigning Add Slow Motion mode to the function button on the KeyMission 170’s remote control and pressing the function button to activate the feature while shooting. The slow motion mode captures footage as a high-frame-rate movie.
- Add Starbursts
- Add Starbursts is a Picture Play feature that is available on select COOLPIX digital cameras. Choosing it will cause star-like rays of light to radiate outward from bright objects such as sunlight reflections or street lights. This effect is suitable for night scenes.
- Add a Bubble Effect
- Add a Bubble Effect is a special effect found in select Nikon COOLPIX cameras such as the S32, it allows you to add a bubble effect to your images, so your subject will look as if it is projected on a bubble. A guide will be displayed in the monitor, and you simply compose your shot so the subject is within the guide.
- Add a Cartoon Effect
- Add a Cartoon Effect is a special effect found in select Nikon COOLPIX cameras such as the S32. When chosen, the camera performs tone compensation to make the image appear like a cartoon.
- Add a Neon Effect
- Add a Neon Effect is a special effect found on select COOLPIX cameras such as the S32, which when chosen, makes the outlines of a subject appear to glow with neon tubing.
- Adjustable Zoom Speeds
- Certain 1 NIKKOR lenses feature adjustable zoom speeds, for versatility when shooting both stills and movies.
- Advanced Movie Mode
- The Advanced Movie Mode allows you to film slow-motion or HD movies in PSAM modes on select Nikon 1 cameras including the V2.
- Airplane Mode
- Airplane Mode disables all wireless or GPS connections on a camera. Select Nikon COOLPIX cameras have built-in GPS or wireless connectivity and must be placed in airplane mode when flying in a plane, in hospitals and other such locations.
- Aliasing
- A type of digital image distortion most often seen when straight lines or edges in a digital image are enlarged to the point at which they appear jagged.
- Ambient Light
- The natural light in a scene.
- Angle of Flash Coverage
- The measurement in degrees of the angle formed by lines projecting from the center of the flash to the extremities of the field of coverage.
- Angle of Incidence
- The angle of light hitting a surface. A basic rule of physics says that the angle of incidence equals the angle of reflectance, which means that the angle of the light coming towards the surface is the same as the angle of light reflected off of the surface. For example, if light hitting a surface came from a light source that was on a 45 degree angle from the surface, the light reflecting off of the surface would travel on a 45 degree angle as well.
- Angle of Reflectance
- See Angle of Incidence.
- Angle of View
- See Picture Angle.
- Anti-Aliasing
- An optical process that samples the edges of an image to fill in the missing areas that cause a jagged appearance.
- Anti-Reflective Coating
- Pertaining to binoculars. A coating applied to lenses to improve the brightness, color and contrast of the image. Quality, type and method of coating applied is of critical importance to brightness, clarity and contrast. Nikon coats all lens surfaces within the binocular/scope for maximum light transmission.
- Aperture
- The circular opening inside the lens that can change in diameter to control the amount of light reaching a camera's sensor or film. The diameter is expressed in numbers called f/stops; the lower the number, the larger the aperture opening.
- Aperture-Priority Auto Exposure
- A shutter speed that is automatically selected by the camera to match the photographer's manually set lens aperture for a correct exposure. Especially useful for controlling depth-of-field.
- Apparent Angle of View
- The segment of a 360° circle that appears to be in view, factoring in the magnification of the binocular. It is calculated by multiplying the magnification by the real angle of view. Binoculars with apparent angles of view greater than 60° are termed wide-angle instruments.
- Apparent Field of View
- Apparent field of view is the angle of the magnified field when you look through binoculars. The larger the apparent field of view is, the wider the field of view you can see even at high magnifications.
- Application
- A computer program, such as an image editor or image browser.
- Applications (Apps)
- The COOLPIX S800c digital camera features the Android platform, which runs apps or applications that can be downloaded to the camera, for shooting and sharing of digital images and video.
- Archival
- The ability of a material, including some printing papers and compact discs, to last for many years.
- Aspect Ratio
- The width of an image divided by its height. In still photography, common aspect ratios are 4:3 (images from digital cameras) and 3:2 (images from film cameras).
- Aspherical Eyepiece Lens
- A non-spherical shaped lens used to minimize aberration and maximize the flatness of field in certain binocular models.
- Aspherical Lens
A lens with a curved, non-spherical surface. Used to reduce aberrations and enable a more compact lens size. Aspherical lenses minimize coma and other types of lens aberrations, even when used at the widest aperture. They are particularly useful in correcting distortion in wide-angle lenses and help contribute to a lighter, more compact design by reducing the number of standard (spherical) elements necessary. Aspherical lens elements correct these distortions by continuously changing the refractive index from the centre of the lens.- Astigmatism
- One of Seidel's five aberrations. Astigmatism is an aberration that causes points to blur, degrading sharpness. It can be reduced but not eliminated by stopping down the lens.
- Astrophotography
- Astrophotography is the specialized type of photography done of the night sky, stars, planets, and other celestial objects. Lunar and Solar eclipses as well as star trails also fall under Astrophotography. Specialized equipment may be necessary in photographing certain celestial subjects like telescopes, solar filters, etc.
- Audio Monitoring
- Using a visual display or auditory (using headphones) to monitor audio levels. This helps keep audio levels at their optimum level. It also helps to minimize degradation. Volume Unit (VU Meter) and Peak Program (PPM Meter) are common types of meters used to measure audio levels. They can be hardware or software based; regardless of type, the scale and ballistics of the meter are important characteristics.
- Auto Area AF
- Auto Area AF is one of Nikon's AF Area Modes. Auto Area AF uses color information and special face recognition algorithms to automatically focus on an individual's face, which is extremely helpful when there's simply no time to select a focus point, or when using Live View in hand-held mode at high or low angles.
- Auto Distortion Control
- When you take pictures underwater, the water itself sometimes causes distortion to occur. The Auto Distortion Control, available on select cameras, automatically compensates for this.
- Auto Exposure (AE)
- In Auto Exposure mode, the camera automatically adjusts the shutter speed and aperture for the optimum exposure for the scene being photographed.
- Auto FP High-Speed Sync
- Auto FP High Speed Sync is a flash mode used for fill-flash photography under brightly lit conditions. It will fill in and open up shadowed areas in order to portray the greatest detail in subjects. It's also ideal when using wide aperture lenses, and because it allows fast shutter speeds—up to fastest shutter speeds on compatible Nikon D-SLRs—it is often used for action-stopping sports photography. And for portraits, you can open up your lenses to their full aperture in order to isolate your subject against a blurred background without overexposing the image.<br /><br />When Auto FP High Speed Sync is selected, the flash will fire for the duration of the shutter curtain's travel, thus syncing with the camera's shutter speed when that speed is set higher than the camera's normal sync speed.
- Auto ISO
- Auto ISO or ISO Auto is a feature that allows you to tell the camera to choose which ISO to use if certain parameters are met. For instance, when there is enough light to use ISO 100, the camera does so, but when it would have to use too slow a shutter speed, then it automatically increases the ISO to 200 and maintains a high enough shutter speed to avoid camera shake. Some Nikon digital cameras let you choose from a range that you're willing to shoot within, such as ISO 400 – 800.
- Auto Slow Sync
- Auto Slow Sync is a flash mode that is used when shooting portraits at night.
- Auto Slow Sync Red Eye
- Auto Slow Sync Red-Eye is a flash mode that combines Red-Eye reduction with Slow Sync. It is used when shooting portraits against a backdrop of night scenery. Use of a tripod is suggested, to prevent blurring caused by camera shake.
- Auto White Balance
- In Nikon D-SLRs, Auto White Balance combines with the Scene Recognition System to analyze each scene's light sources, cross-referencing this information with 5,000 actual picture data examples from over 20,000 images in the camera's onboard white balance database. <br /><br />A digital camera's white balance setting compensates for the different colors of various light sources—fluorescent, which has a "green" cast, or a cooler-than-daylight light balance; incandescent, which has a "yellow" or a warmer-than-daylight white balance; and daylight—so that white objects in a scene appear white regardless of the color temperature (the warmth or coolness) of the light source. Even under mixed lighting or difficult light sources like mercury vapor lights, auto white balance technology calculates an ideal white balance for remarkably faithful colors. <br /><br />For a thorough understanding of white balance and how it influences the final image, <a class="none" href="http://www.nikonusa.com/Learn-And-Explore/Photography-Techniques/fubpbfls/1/Setting-White-Balance.html" target="_blank">read Lindsay Silverman's article Setting White Balance</a>.
- Auto-servo AF
- In AF-A or Auto-servo AF, the camera automatically selects Single-servo autofocus if the subject is stationary or Continuous-servo AF if the subject is moving. The shutter will only be released (snap a photo) if the camera is able to focus.
- Autofocus (AF)
- A system of sensors and motors that allow lenses to obtain focus automatically; in some cameras, the system also allows the lens to maintain focus on a moving subject.

- A feature that sets the camera to take a series of pictures (usually three) at different exposure settings.
- Autumn Colours Scene Mode
- This scene mode, available on select Nikon digital cameras, is designed to take vivid photographs of scenes with colourful red and yellow autumn leaves.
- B-Frames
- Bi-directional (B) frames are encoded based on an interpolation from I- and P-frames that come before and after them. B-frames require little space, but can take longer to decompress because they're reliant on frames that may be reliant on other frames. A Group of Pictures (GOP) can begin with a B-frame, but can't end with one.
- BSS (Best Shot Selector)
- An exclusive Nikon technology, Best Shot Selector automatically selects the image with the sharpest focus from a series of up to ten consecutive images; only the sharpest shot is saved to the memory card. <br /><br />When Best Shot Selector is chosen, a series of images are stored in the camera's memory where they are evaluated by the camera's computer. The single image with the highest level of detail is then automatically transferred to the memory card.
- Back Arrow
- Use the back button to return to the previous screen you were on, when using the COOLPIX S800c digital camera.
- Back Focus
- Back focal distance, meaning the distance from the tip of the lens' furthest rear surface to the film/image sensor surface where the image is focused.

- Bit
- A unit of measurement indicating the information capacity of one binary digit.
- Bitmap
- A pixel-by-pixel description of an image, where each pixel is a separate element.
- Blink Proof
- When using this feature, the camera detects that a human subject may have closed their eyes immediately after it recognizes the face. When this happens, the "Did someone blink?" screen will be displayed on the monitor to check the picture taken.
- Blinking Highlights
- A feature of Nikon digital SLR cameras, the blinking highlights display indicates areas of the photograph in which highlight detail is missing.
- Blossom Scene Mode
- A scene mode available on select Nikon digital cameras that is designed for taking great photos of fields of flowers or other landscape that are full of blossoming flowers.
- Blu-ray Disk
- Blu-ray (BD) is an optical disk storage medium superseding the DVD format. It can store six times more data than a DVD. The name refers to the blue laser used to read the disk. Blu-ray disks normally have a capacity of 25 gigabytes. Double sided Blu-ray disks have a capacity of 50 gigabytes.
- Bluetooth
- Bluetooth is a proprietary open wireless technology standard that is used for the exchange of data over short distances. Bluetooth can connect several devices together, whether fixed or mobile. Bluetooth is often used to connect wireless communication devices (cellphones) with other devices such as an earpiece/microphone for talking on a Bluetooth compatible cellular phone. The COOLPIX S800c digital camera offers Wi-Fi and Bluetooth connectivity.
- Blur
- A way of softening an image or part of an image.

- Buffer
- Memory in a camera or digital device that stores information before it is written to a storage source.
- Buffering
- The action of the digital camera preloading data into a reserved area of its memory. Certain Nikon cameras feature modes that utilize the buffering of image or video data specific to the chosen mode.<br /><br />With regards to the Nikon 1 camera system, the camera fills the buffer with data before the shutter is fully depressed. When using the Smart Photo Selector mode, the camera stores this pre-recorded data and can access it if the data holds the best shots taken. When using the Motion Snapshot mode, the video captured before and after the still image is captured is stored in the camera's buffer for use in creating the final Motion Snapshot.
- Built-in World Map
A scene mode available on select Nikon digital cameras that lets you view maps that are built-into the camera's memory.- Bulb (B Setting)

- A phenomenon in which light rays passing through a lens focus at different points, depending on their wavelength. Axial chromatic aberration is a variation in focal length; lateral chromatic aberration, a variation in magnification. Lateral chromatic aberration: Light wavelengths differ depending upon color. Differences in the length of the wavelengths result in changes in image magnification and become visible at image peripheries. Lateral Chromatic Aberration is the cause of color fringing. Lateral chromatic aberration is reduced to some degree by combining different lens elements with different refractive indexes, but optically speaking, it cannot be completely eliminated. In addition to red and its complimentary color, cyan, and blue and its complimentary color, yellow, some lenses may exhibit complex color fringing that combines these two primary types. It is greatly reduced by low-dispersion ED glass.
- Cinematographer
- A person who uses a motion picture camera to record the actual film footage shot during the making of a motion picture. Director of Photography is an equivalent title. On large budget "Hollywood" productions, cinematographers or director's of photography are responsible for the artistic and technical decisions related to capture of the film (or digital video, as many of today's motion pictures are being recorded using digital capture devices.)
- Cinematography
- The art and science of photographing a motion picture. The cinematographer is responsible for capturing the actual film footage using a motion picture camera which can be film or digital based.
- Circle of Confusion
- In photography, the circle of confusion (CoC) is used to determine the depth of field, the part of an image that is acceptably sharp. A standard value of CoC is often associated with each image format, but the most apprpriate value depends on visual acuity, viewing conditions and the amount of enlargement. Properly, this is the maximum permissible circle of confusion diameter limit, or the circle of confusion criterion, but is simply called circle of confusion.<br /><br />Real lenses do not focus all rays perfectly, and so, even at best focus, a point is imaged as a spot rather than a point. The smallest such spot that a lens can produce is often referred to as the circle of least confusion.
- Circular Polarizing Filter
- Converts linear polarized light waves to circular polarized light waves. Required whenever polarizing is desired using autofocus cameras and cameras that have semi-silvered reflex mirrors.

- Cloudy is a white balance setting. When manually setting the white balance on your digital camera, and shooting under cloudy lighting conditions you use the cloudy setting to balance the available light so it is captured correctly by the camera.
- Codec
- A term related to digital video, a codec is a device or computer program that is capable of encoding and/or decoding a digital data stream or signal.
- Colour Cast
- If the white balance of a scene does not match the lighting under which the scene is being photographed, a colour cast can occur. For example, daylight is normally cooler than incandescent lighting, so if you photograph a subject lit by an incandescent light and the white balance of the camera is set for daylight, the image will look warmer because that type of lighting is warmer (orangeish) in color than daylight. If the camera was set for incandescent and you photograph a subject in daylight, the image would look cooler (blueish). When shooting RAW (NEF), you can readjust the white balance in Nikon Capture NX2 in post production.
- Colour Conversion Filter
- A filter that alters the colour temperature of light to make it suitable for the film in use. It enables you to use daylight-type film indoors or tungsten-type film outdoors.

- Comprehensive Dust Reduction System
- Special care should be taken when changing lenses in order to avoid the possibility of dirt or dust entering the camera. Once inside the camera, foreign matter may adhere to the low-pass filter and show up in photographs. To help prevent the appearance of these artifacts in photographs Nikon has created the Comprehensive Dust Reduction System. This system uses a series of high resonance frequencies to vibrate the optical low-pass filter. This dislodges dust on the front of the sensor and reduces dust spots appearing on images. This system combined with the existing Image Dust Off system in Capture NX 2 provides a full dust prevention system for photographers.<br /><br />Sensor cleaning can be set to be performed manually when required by selecting the 'Clean now' setting, or automatically by selecting the 'Clean at startup/shutdown' setting. The 'Clean at startup/shutdown' setting has options for when the camera automatically performs an automatic sensor clean, either each time the camera is turned on, turned off or both.<br /><br />Sensor cleaning takes approximately three seconds to complete. If the shutter release is depressed during a sensor clean, cleaning will be cancelled. This enables images to be taken even if a sensor clean has started.

DX designates the incorporation of a DX format CMOS image sensor in a COOLPIX digital camera. Using a DX sensor brings DX image quality to the form factor of a COOLPIX camera.- DX Format
- Refers to Nikon cameras that feature a 1.5 magnification factor imaging sensor. Nikon digital SLRs have either an FX or a DX sensor. The FX sensor, measuring 23.9 x 36mm, is roughly equivalent to the size of the 35mm film frame. The DX sensor is smaller, measuring 15.8 x 23.6mm. The DX sensor makes possible the production of lighter, smaller cameras, but because it covers a smaller portion of the image projected by the lens, a 1.5x crop factor (so called because the smaller sensor crops the image compared to an image from a 35mm film frame) is introduced. This means, for example, a 24mm lens on a DX sensor camera will provide an approximate 36mm view.
- DX-Coded Film
- Film that features embedded information that allows the camera to automatically set the film's speed.
- Dach (Roof) Prism Binoculars
- “Dach” means roof in German. The optical path at the objective side and eyepiece side is virtually straight, making it possible for the binoculars to be compact and slim.

- Dynamic Area AF
- Dynamic Area AF is one of three Nikon AF Area Modes. With Dynamic Area AF, you can select from several focusing options: 9-, 21- or all 51-point AF. Select a Single AF point and the areas surrounding it serve as backup—a significant advantage when shooting moving subjects. Select the 9-point option when you want to focus on erratically moving subjects with greater accuracy. When dealing with insufficient contrast for fast focus detection, choosing 21 or 51 points makes detection easier. The 51-point option also allows for 3D Focus Tracking, which uses color information from the RGB metering sensor to automatically follow moving subjects across the AF points.
- Dynamic Fine Zoom
Dynamic Fine Zoom is a new feature available on select Nikon COOLPIX digital cameras that extends the zoom range electronically 2x with minimal image degradation.- Dynamic Range
- Photographers use "dynamic range" for the luminance range of a scene being photographed, or the limits of luminance range that a given digital camera or film can capture. The dynamic range of sensors used in digital photography is many times less than that of the human eye and generally not as wide as that of chemical photographic media
- E-Compass
- The E-Compass is a general use compass feature that allows you to use the COOLPIX AW100's GPS as a compass, and it can assist you in finding your bearings. When the Compass display is set to ON, it is displayed on the shooting screen.

- Flash Card
- A type of camera memory card that can retain data after the system has been turned off. Also known as a flash memory card or media card.
- Flash Colour Information Communications
- Nikon Speedlights provide improved colour accuracy in flash photography thanks to flash colour information communication. In Auto White Balance mode, the master Speedlight—the unit attached to the Nikon DSLR, transmits information to the camera about the colour temperature of the light that it is emitting. The information is used by the camera to determine a white balance setting that best matches the colour temperature of the flash to the colour temperature of the scene's ambient light, thus allowing the camera to achieve optimum white balance for the scene.
- Flash Duration
- Refers to the very short amount of time it usually takes for a flash to fire. Automatic flash control varies the brightness by varying the duration of the flash. Flash duration for an auto flash is typically 1/1000 to 1/20,000 second.

- Flourescent is a white balance setting. When manually setting the white balance on your digital camera, and shooting under flourescenet lighting you use the flourescent setting to color color balance the light so it is captured correctly by the camera.
- Fluorescent
- <p>The illumination produced from a gas-discharge lamp or tube is called fluorescent light. Electricity to the lamp stimulates the mercury vapor within the lamp creating the emission of electromagnetic radiation which produces the fluorescence. This type of lighting is typically found in office buildings, warehouses and industrial settings. The light produced is “green” or a cooler-than-daylight light balance. Setting a camera’s white balance to Fluorescent will correct for the green cast.</p><p>In terms of color temperature, fluorescent light generally falls between 4000 and 5000 degrees Kelvin.</p><table cellspacing="0" cellpadding="0" width="456" border="1"><tr><td width="156"><p align="center"><strong>Color Temperature</strong> </p></td><td width="300"><p align="center"><strong>Light Source</strong> </p></td></tr><tr><td width="156"><p align="center">1000-2000 K</p></td><td width="300"><p> Candlelight</p></td></tr><tr><td width="156"><p align="center">2500-3500 K</p></td><td width="300"><p> Tungsten Bulb (household variety)</p></td></tr><tr><td width="156"><p align="center">3000-4000 K</p></td><td width="300"><p> Sunrise/Sunset (clear sky)</p></td></tr><tr><td width="156"><p align="center">4000-5000 K</p></td><td width="300"><p> Fluorescent Lamps</p></td></tr><tr><td width="156"><p align="center">5000-5500 K</p></td><td width="300"><p> Electronic Flash</p></td></tr><tr><td width="156"><p align="center">5000-6500 K</p></td><td width="300"><p> Daylight with Clear Sky (sun overhead)</p></td></tr><tr><td width="156"><p align="center">6500-8000 K</p></td><td width="300"><p> Moderately Overcast Sky</p></td></tr><tr><td width="156"><p align="center">9000-10000 K</p></td><td width="300"><p> Shade or Heavily Overcast Sky</p></td></tr></table>
- Fluorine Coat
Photographers need gear that can withstand the elements. Nikon’s fluorine coat effectively repels dust, water droplets, grease or dirt, ensuring easy removal even when they adhere to the lens surface. Nikon’s fluorine coat endures a high frequency of lens surface wiping and its anti-reflective effect also contributes to the capture of clear images.- Fluorite Lens Element
Fluorite (FL), a lightweight mono-crystal optical material, has excellent optical properties while reducing overall lens weight to improve balance and handling, especially useful in longer focal length lenses.- Focal Length
- The distance from the principal point to the focal point.
- Focal Length Multiplier
- For a D-SLR that uses an imaging sensor smaller than full frame (35mm film frame), the ratio of the diagonal of the camera's imaging sensor in comparison to the diagonal of a 35mm frame is the crop factor. This ratio is commonly referred to as a focal length multiplier (FLM), since multiplying a lens focal length by the crop factor or FLM gives the focal length of a lens that would yield the same field of view if used on the reference format.
- Focal Plane
- The precise position (plane) within the camera body, behind the shutter curtain, at which the light gathering surface of the image sensor is fixed. In a film SLR, this is the same plane across which the film would be positioned for each exposure.

- GPS
Global Positioning System, in which the receiver calculates its position on the earth by timing signals received from GPS satellites.- Gamma
- Gamma is a mathematical term which is used to describes a skew in the middle tones of an image. Gamma values do not affect the overall density range (in other words the brightest and darkest points of the color space) but will dramatically affect the overall appearance: A low gamma value will produce a saturated, somber image, whereas a higher value will result in a de-saturated, washed-out result. All imaging devices such as monitors, digital cameras and scanners make use of some sort of gamma value as the conversion between digital and analog. The value of gamma can be specified for a color space so that the correct tonality can be reproduced.
- Gelatin Filter
- A color filter made of gelatin. Since gelatin can be dyed with a wide range of materials, filters can be made with a variety of colors for various effects. Certain lenses, such as the NIKKOR 10.5mm Fisheye lens, accept gelatin filters. Nikon does not make gel (gelatin) filters. Most Gel filters are made by Kodak (under the "Wratten" brand name) but other manufacturers also supply gel filters. These filters can be purchased from specialty camera stores and they usually come in 3" x 3" or 4" x 4" sheets. These sheets should be custom-cut by the user for the desired application. Many different types are available for color correction and neutral density effects.
- Geotagging
- Geotagging is the practice of recording and sharing GPS coordinates captured at the time that photos or videos are shot. Some photographers like to keep detailed records of exactly where they have traveled and photographed; while other photographers like to share the GPS coordinates with others so they too can visit these locations.
- Ghost Image or Ghosting
- A double image that results from using flash in relatively bright light at a low shutter speed. The two images, one from the ambient light and a second from the flash, do not perfectly coincide.

- Grayscale
- A term used to describe an image that contains multiple shades of gray, as well as black and white. Often used in imaging programs as a synonym for black-and-white.
- Group Area AF
- With Group-area AF, the camera focuses using a group of five focus points (the center one is not shown when the Group-area AF focus points are illuminated) selected by the user. This reduces the risk of the camera focusing on the background instead of on the main subject. Choose this mode for subjects that are difficult to photograph using a single focus point. If faces are detected in AF-S focus mode, the camera will give priority to portrait subjects; or when no faces are present, focuses on the closest subject to the camera.
- Groups of Pictures
- MPEG formats use three types of compressed frames, organized in a group of pictures, or GOP, to achieve interframe compression. GOPs are defined by three factors: their pattern of I-, P-, and B-frames, their length, and whether the GOP is “open” or “closed.”
- Guide Mode

- A combination of Lens Shift and Electronic Vibration Reduction for image stabilization. Found in Nikon COOLPIX cameras. First, camera shake is corrected with the Lens Shift VR. If further image correction is required, the camera automatically takes two shots, one with a small amount of blurring taken at a faster than normal shutter speed, and another with a large amount of blurring taken at the normal shutter speed (the image with camera shake). It then aligns the two images to detect how much each pixel has moved. An appropriate amount of blurring, noise and chroma is extracted from each image, and a stabilized image is produced by processing the images while altering the synthesis ratio of both images. This method is most effective with large amounts of blurring. Some Nikon COOLPIX cameras use image processing to correct blurring without taking two shots.<br />
- Hyper Read
Laser provides quick and stable measurement response regardless of distance (approximately 0.3 seconds).- Hyperfocal Distance
- The closest point you can focus a lens and still have the depth-of-field including infinity when the lens is focused on infniity. On a NIKKOR lens that does not have a depth-of-field scale, you can calculate the hyperfocal distance by using the formula: H = f 2 / ( F x CoC ) where "H" is the hyperfocal distance in mm, "f" is the focal length, "F" is the aperture and "CoC" is a Circle of Confusion value (0.033 for 35mm film or an FX format camera or 0.020 for a DX format body). The maximum permissible circle of confusion will vary depending on the image reproduction size, image capture format and other variables.
- I-frames
- Intra (I) frames, also known as reference or key frames, contain the necessary data to re-create a complete image. An I-frame stands by itself without requiring data from other frames in the Group of Pictures (GOP). Every GOP contains one I-frame, though it doesn't have to be the first frame of the Group. I-frames are the largest type of MPEG frame, but they're faster to decompress than other kinds of MPEG frames.
- ID Technology
Delivers the one number you need for your best chance at factoring in relevant angles.- IF Lens
A NIKKOR lens in which only the internal lens group shifts during focusing. These lenses will be designated with the abbreviation IF on the lens barrel.- IPTC
- ITPC stands for the International Press Telecommunications Council. The ITPC came up with the Information Interchange Model or IIM file structure and metadata attributes that can be applied to images as well as text and other types of media files. It is almost universally accepted by photographers as the standard format for embedding metadata into an image file. Such embedded metadata could include the photographer's name, copyright information, or other descriptions. Almost all of the IIM attributes are supported by EXIF. ITPC data is found in the ITPC Header and is compatible with JPEG and TIFF files. In recent years, XMP (Extensible Metadata Platform) has taken over as the defacto standard format for embedding this data in an image file.
- IPTC Presets
- In select Nikon D-SLR cameras, IPTC presets can be imported into the camera before shooting, so as images are saved, the IPTC data is written to them, saving editors and photographers a great deal of time doing this in post-production.
- ISO

Maximum high ISO available on the camera is 3200 ISO.- ISO 6400
Maximum high ISO available on the camera is 6400 ISO.- ISO Control
- Selected Nikon D-SLRs offer auto ISO control, a feature that will maintain a selected shutter speed range. Here's how it works: In aperture-priority operation, for instance, choose ISO control and set a base shutter speed of, for example, 1/250 second—meaning that you don't want the shutter speed to go below that setting. When the light level in the scene requires a shutter speed slower than 1/250 second, the camera will automatically kick up the ISO to maintain that shutter speed.<br /><br />Along with f/stop and shutter speed, ISO is an important element of exposure control.
- Image Area Selection
- Image Area Selection is a feature available on the select Nikon Speedlight flashes such as the SB-900. When mounted on a camera that can select an image area between FX-format (36x24) and DX-format (24x16), the Speedlight automatically selects the suitable light distribution angle in accordance with the camera’s image area setting.

- In-Camera HDR
- Select Nikon cameras have an in-camera HDR (High Dynamic Range) mode so make sure to review your reference manual for complete details on setting your camera for HDR.
When shooting HDR, the camera automatically combines two exposures to form a single image that captures a wide range of tones, from shadows to highlights. The first exposure is darker (underexposed) and the second exposure brighter (overexposed). They are combined into one image that has a wider range of tones than can be captured in one exposure. HDR mode is only available with JPEG recording, not RAW (NEF) recording.
Along with choosing the exposure difference, the user is given the choice of Smoothing (high, normal or low). Smoothing refers to the look of the composite HDR image. High and normal produce a more natural look, whereas low produces an image with a more surreal look.

It is generally regarded as the most accurate metering for most lighting situations, including those with complex lighting. Matrix Meter or 3D RGB Color Matrix Meter gathers information from the red, green, and blue sensors and factors in distance information provided by the lens as it evaluates proper exposure calculation. This meter instantly analyzes a scene's overall brightness, contrast, and other lighting characteristics, comparing what is sees against an onboard database of over 30,000 images for unsurpassed exposure accuracy, even in the most challenging photographic situations. By the time the 3D Matrix meter has made its considerations of colors by hue and saturation, tonal ranges by brightest and darkest, areas of similar tonality that are connected or separated, distance to the subject, and compared that to its database generated from photographic images, it's got a very good idea of what the exposure should be.<br /><br />If you are a beginner, Matrix is where you should start. As your skills grow, and they will, you will acquire a better understand of when it might be beneficial to use other light metering options.<br /><br />What is the database of over 30,000 images? Over the years Nikon has studied the color, area of coverage, focus distance, contrast, size and shape of shadows and highlights and exposure characteristics of over 30,000 actual photographic images and incorporated this data as a reference source for the expert exposure system that is the 3D Color Matrix Meter.

- Meniscus Glass
- Nikon's exclusive protective glass for NIKKOR lenses comes attached to the front of fast super-telephoto lenses. Normal flat protective glass lets incoming light reflect off the surface of the image sensor or film, especially under a strong light source such as a spotlight. This then reflects again off the protective glass, resulting in a ghost effect. Nikon's curved meniscus glass dramatically reduces this re-reflected light, realizing clearer images with less ghosting.
- Meso Amorphous Coat
- Meso Amorphous Coat* realizes the highest anti-reflection performance in NIKKOR history. Meso Amorphous Coat provides an effect superior to that of Nano Crystal Coat for diagonal incident light, and an effect equivalent or superior to ARNEO Coat for vertical incident light. With its superb performance, ghost and flare caused by incident light from various directions are noticeably reduced, delivering clear images even under harsh conditions.
*With this coating system, amorphous particles, that are even smaller than nano particles, are utilized to create even more gaps within the coating to form an ultra-fine mesoporous structure, attaining a lower refractive index. In addition, a higher-precision base coat is employed to further enhance the anti-reflection effect.

The latter of these modes provides a unique 2.7x crop factor by cropping the center of the image sensor to exactly 1920 x 1080 pixels. All three crop modes produce the same resulting 1080p movie files. These modes provide unparralleled versatility to any collection of NIKKOR lenses by offering a multitude of cropping options to fit almost any shooting situation and all provide the same high quality 1080p output movie file.
- Multilayer Coating
Multilayer coating is applied to one or more lens and prism surfaces.- Multiple Exposure: Lighten
- Multiple Exposure Lighten is a Scene mode in select Nikon digital cameras. When using this mode, the camera will automatically capture moving subjects at regular intervals and compare each image, then create a single composite image that combines only the bright areas. Use this mode for photos of the light trails from cars or other moving objects or star trails.

- NEF - Nikon Electronic Format
- Exclusive to Nikon cameras, the NEF is Nikon's RAW file format. RAW image files, sometimes referred to as digital negatives, contain all the image information captured by the camera's sensor, along with the image's metadata (the camera's identification and its settings, the lens used and other information). The NEF file is written to the memory card in either an uncompressed or "lossless" compressed form.
The primary benefit of writing images to the memory card in NEF format rather than TIFF or JPEG is that no in-camera processing for white balance, hue, tone and sharpening are applied to the NEF file; rather, those values are retained as instruction sets included in the file. You can change the instruction set as many times as you like without ever disturbing the original image's RAW data. Another benefit of the NEF file is that depending on the camera, it retains 12-bit or 14-bit data, resulting in an image with a far greater tonal range than an eight-bit JPEG or TIFF file.
After-capture processing of the NEF file by Nikon's Capture NX2 software, or other imaging programs, offers greater control over the final image than the processing of a JPEG or a TIFF. After processing, the NEF file can be saved as a TIFF, JPEG or again as a NEF with the addition of any applied Capture NX2 processing saved inside the file as a second or alternate instruction set. As long as the original NEF file is preserved, the "digital negative" remains untouched; processing a NEF file does not alter the original instruction set.

- Nano Crystal Coat
An anti-reflective coating developed by Nikon that virtually eliminates internal lens element reflections across a wide range of wavelengths. Nano Crystal Coat uses ultrafine, nano-sized* crystal particles to eliminate reflections inside the lens throughout the spectrum of visible light waves (380 to 780 nm) in ways that far exceed the limits of conventional antireflection coating systems. Nano Crystal Coat not only solves ghost effects caused by red light, which was incredibly difficult for previous systems. It also effectively reduces ghost and flare effects caused by light entering the lens diagonally. The result: clearer images.- Negative Film

- Phase Fresnel
Phase Fresnel (PF) lens elements effectively compensate for chromatic aberration and ghosting when combined with ordinary glass lens elements. The PF lens element is based upon the Phase Fresnel lens, which appears to have a series of concentric circles engraved onto it. Utilizing a Phase Fresnel lens element allows Nikon engineers to use fewer lens elements, resulting in a more compact and lightweight lens. Due to the characteristics of a PF (Phase Fresnel) lens that utilizes the photo diffraction phenomenon, when there is a strong light source within the frame or when light enters the lens from outside of the frame, ring-shaped coloured flare may occur according to shooting conditions. This phenomenon can be minimized with “PF Flare Control” to be included in Capture NX-D (ver.1.1.0 or later). For more information, see software Help/manual. Capture NX-D is available from the Nikon website. Be sure to keep your software up to date.- Phase-Coating

- Pertaining to binoculars. Relative brightness value is obtained by squaring the diameter of the exit pupil. The greater the relative brightness is, the brighter the image will be.
- Relative Illumination
- Illumination around the periphery of the image field. Used as a comparison of the brightness between the center and the periphery.
- Release-Priority AF
- An autofocus mode in which the shutter can be released anytime, even if the subject is not in focus. Recommended in fast-moving situations when you do not want to miss any of the action.
- Rembrandt Lighting
- A studio lighting technique for portraits that was first characterized by the painter Rembrandt. In Rembrandt lighting, the shadow side of the face shows a diamond shaped area of illumination under the eye. It is done by positioning a main light to one side of the subject and a reflector or less powerful light on the opposite side. It is an easy lighting set up and looks natural.
- Removable Memory
- A solid-state removable memory card for a digital camera that comes in a variety of size and capacity configurations. The larger the card's capacity, the more digital pictures it can store.
- Repeating Flash
- A feature available in some flash units that fires the flash many times while the shutter is open, during a brief exposure, producing a strobe-light effect. In this mode, the photographer can control the flash output, number of times the flash fires, and how often the flash fires.
- Reproduction Ratio
- Specifically the size of the image recorded on film divided by the actual size of the subject.
- Resolving Power (Resolution)
- The ability of a lens or photographic material to reproduce small details. One of the measurements of lens performance.
- Retractable Lens Barrel
- Select 1 NIKKOR lenses in the Nikon 1 camera system are designed specifically with a retractable lens barrel, for more compact storage when the lens is not being used. A button on the lens barrel is depressed, and the zoom ring rotated to extend the lens barrel for use. And turns the camera on.
- Retrofocus-Type (Wide-Angle) Lens
- It is a lens which has the principal point behind the rear part of the entire lens. The design is like the reverse of a telephoto lens (thus called "retro"), and since the back focus (back focal distance) can be obtained longer than the focal length, it is used mostly for SLR wide-angle lenses. Compared to symmetrical wide-angle lenses, the brightness of the edge of the image field is great, but the distortion is bigger. From the outside, the front lens element is large and the aperture blade appears larger when seen from the front.

Useful for copystand work and when the camera is inconveniently positioned low, near the ground, or at an angle which makes normal viewing impossible. Provides an upright, unreversed image for right angle viewing. Individual eyesight adjustments are possible. They allow you to set the reproduction ratio to either 1:1 or 1:2.
- Rim Lighting
- Rim lighting is achieved by placing a light behind the subject, so the rim or outline of the subject's body is illuminated.
- Ring Light
- A type of flash or strobe in which the flash unit is ring or circular shaped. A Ring Light fits around the camera's lens and provides soft, even lighting with no shadows. This type of light is most often used for macro or close-up photography, but can also be used for fashion portraiture and industrial or medical photography.
- Roof Prism Binoculars
- “Dach” means roof in German. The optical path at the objective side and eyepiece side is virtually straight, making it possible for the binoculars to be compact and slim. They are more costly to produce because their very small prisms require special grinding and polishing to maintain image integrity.
- Route Shooting
- Route shooting is a feature of the KeyMission 80 action camera that allows you to set the camera to record still images or movies as your experiences unfold. If you choose still images, the camera takes up to 100 stills within a specified shooting time.

Nikon COOLPIX cameras are so smart they know what kind of picture you're taking and can automatically select from six commonly used scene modes, eliminating the mode-setting procedure and streamlining the shooting process.- Scene Effect
- Incorporated into select Nikon COOLPIX cameras, the Scene Effect is an adjustment slider that allows you to adjust the intensity of certain scene modes. For example, the Food scene mode scene effect affects picture color, letting you make images more blue or more red; the Landscape and Close-up scene modes affect the saturation of the image, letting you choose between more vivid and less vivid; and the Sunset and Dusk/Dawn scene modes Scene Effect alters color, letting you choose to make the image more red or more blue.
- Scene Modes
- A mode in which camera settings are adapted to a specific scene or type of subject. The scene modes automatically selects the appropriate exposure (shutter speed, ISO, aperture) for the particular scene the photograph is being taken in. Many COOLPIX cameras have upwards of 18 scene modes. Some Nikon D-SLRs also offer scene modes. Some of the many Nikon Scene modes are: scene auto selector, portrait, landscape, sports, night portrait, party/indoor, beach, snow, sunset, dusk/dawn, night landscape, close-up, food, museum, fireworks show, copy, backlighting, panorama assist, candlelight, pet portrait, blossom, autumn colors, silhouette, high key, and low key.
- Scene Recognition System
- Nikon's Scene Recognition System (SRS) recognizes the position, color, tones and characteristics of a subject or overall scene prior to capture; then, using information from the sensor, compares that information to the camera's built-in image database to achieve more accurate autofocus, auto exposure and auto white balance control. <br /><br />The Scene Recognition System's accuracy and precision are made possible by the image recognition capability of the sensor. Data supplied to the camera's system by the RGB sensor includes subject tracking and identification, highlight analysis and light source identification. <br /><br />Even changes of subject position within the viewfinder can be recognized as image information, and this capability is used by the autofocus system as a 3D-tracking function to give greater priority to the subject’s position. For subject tracking, the sensor recognizes the color of a subject within a user-selected focus point, then follows the subject’s movement by detecting the identical color segment. The 3D-tracking mode shifts the focus point automatically to respond to the subject’s movements. The AF and SRS are in constant communication with each other, improving tracking performance even for subjects quickly approaching the camera.<br /><br />As an auto white balance function, better image recognition combined with an advanced auto white balance algorithm achieves higher-performance white balance control.<br /><br />For subject identification, the SRS uses color information from the sensor to automatically detect people and skin tones. In this way it can quickly focus on the most important element—the human face—in Auto area AF mode. Even if similar colors exist both in the foreground and background, the Scene Recognition System uses distance information from a D- or G-type AF NIKKOR lens to determine where the main subject is.

Depending upon the camera, you may be able to choose the playback times of 2x faster, 4x faster, 10x faster, 20x faster, 25x faster, or 30x faster than normal. Recording a movie at 1080/30p for 29 minutes and choosing 30x faster Superlapse movie playback will give you a final movie of about 58 seconds in length.
- Switching Illumination Patterns
- The SB-900 and SB-700 Speedlights offers the choice of three light output patterns—standard, center-weighted and even—to provide flash illumination for almost every shooting situation. The standard pattern is basic illumination for usual flash shooting environments. The center-weighted pattern provides larger guide numbers at the center of the image than other illumination patterns at the same focal length, making it particularly suitable for portraits. With the even pattern, the light falloff at the edge of the image is less than with the standard illumination pattern, making the pattern ideal for shooting group photographs indoors.
- Sync Speed
- The speed at which a flash synchronizes with the opening of the shutter. Normal X-sync flash operation requires the entire shutter to be open when the flash is fired. Shutter speeds at which this is possible are referred to as sync speeds.
- T or T Setting

They are designed to automatically set the camera's f/stop, shutter speed and, often, auto flash, to produce a balanced exposure of the subject.
The Vari-Programs vary depending upon which D-SLR you are using. In certain Nikon D-SLRs, the Vari-Programs also involve the camera's image processing engine to tailor, for example, white balance, sharpening, tone and hue to the subject. The portrait program's technology, for instance, will set not only a shallow depth-of-field, but also enhance skin tones.
- Vari-angle LCD Monitor

- Vignette Control
- Vignette Control reduces vignetting for G and D type NIKKOR lenses (DX and PC lenses excluded). Its effects vary from lens to lens and are most noticeable at maximum aperture. Choose from High, Normal, Low and Off. Vignette control does not apply to movies and its effects can't be previewed in Live View. Nikon Capture NX2 software also offers a Vignette Control tool that can be used to correct for vignetting on images that were captured with G or D type NIKKOR lenses. The Vignette Control tool can be used on NEF, JPEG, and TIFF files, however it is most effective when performed on images taken at maximum aperture. If the picture in the active image window is a RAW image taken with a lens equipped to transmit distance information (a type G or D lens) mounted on a camera that can record this information, Capture NX 2 will use the lens information recorded with the image to automatically select an optimal range for the Intensity slider.
- Vignetting
- Slight light falloff in the lens causes vignetting. Due to the physical properties of light passing through lenses it is impossible to get the same amount of light to the edges of the circle as the center (the light going to the edges has to travel further, thus falls off more).This light fall off creates a very slight reduction of exposure on the corners of an image. This darkening in the corners is called vignetting.<br /><br />Because light falls off (decreases) with the square of the distance it travels, light that travels farthest (from the lens to the edge of the circle versus from the lens to the center of the frame) will always be slightly reduced. All lenses exhibit some light fall off towards the edges but wide angle lenses as well as some telephoto zoom lenses are most prone due to their optical design. Further, a lens will generally show the most vignetting at it's widest aperture.<br /><br />With smaller format cameras (such as DX format D-SLRs) the light fall off is less noticeable because only the center of the circle of illumination is used. With larger format cameras (like 35mm film or FX format cameras) more of the circle is used and there will be more difference between the center of the frame and the edges.<br /><br />A second type of vignetting is called Mechanical Vignetting. This is simply vignetting caused by something blocking the light path such as a filter with too thick a mount or stacking several filters together. Also, using the wrong lens hood on a lens can cause mechanical vignetting.<br /><br />In most shooting conditions (proper exposure, normal subjects, etc.) light falloff will be minimal. However, at some f/stops, focal lengths and with some lenses it is normal to have more light falloff. If you have vignetting with a particular shot, change the lens focal length or aperture (lenses shot "wide open" will have the most vignetting, so stopping down a stop or two can help) until the vignetting is minimized. While vignetting may be easy to see and reproduce in a test situation, in real world shooting it is generally invisible.<br /><br />For those conditions where vignetting is obvious in a photo, Nikon View NX software will automatically compensate for vignetting and Capture NX2 software includes a Vignette Control slider to further reduce the visible effect without noticeably changing the overall image.
