Four special features of Nikon digital cameras

Nikon Face-priority AF
Face-priority Auto Focus Industry Leading Technology
Nikon Corporation has released an exciting new technology that makes it easier to take high-quality, sharply focused portraits. Called Face-priority AF (Autofocus), this technology is an industry first.
The Face-priority AF function uses the latest digital technology to automatically detect a person’s face at typical portrait taking distances, then, operating based on real photographic techniques, activates autofocus to focus upon the face area! The One-touch portrait button conveniently located at the top of the camera body makes it much simpler to take better quality pictures by offering easy access to Nikon’s unique Face-priority AF, In-Camera Red-Eye Fix and D-Lighting functions.
Here’s how it works: when you’re ready to take a portrait, select the camera’s One-touch portrait button. A special digital detection program will scan for facial details and then control autofocus operation based on the location of the detected face in the scene. Even if the subject moves, or as the photographer recomposes the picture, Face-priority AF will respond and keep focus on the subject’s face. Manual techniques that formerly required the photographer to use focus lock can be avoided in favour of the new automation of Face-priority AF. It’s faster, responsive to creative composition, and makes portrait picture taking easier than ever.

To use the new technology, Select Portrait Mode on the camera’s mode dial and Face-priority AF will be automatically selected. Compose on the person, which must have their face towards the camera, then, ½ depress the shutter button to activate the camera. As Face-priority AF activates, a square outline on the camera’s LCD will appear around the face, confirming operation; if the photographer decides to recompose the image, Face-priority AF will track the subject’s facial area and will confirm the moving subject by changing color for the square outline and keeping the square outline around the face. When there are two or three people in the scene, Face-priority AF will operate using closest subject priority and the square confirming outline will indicate the closest person in the scene’s composition.

Nikon Best Shot Selector
Best Shot SelectorTM is a Nikon exclusive technology that takes up to 10 shots as long as the shutter release is pressed. The sharpest single shot is saved and the rest is discarded. This feature is useful for minimizing motion blur due to camera shake, especially if the zoom is set to telephoto. The first photo in the series determines focus, exposure, and white balance. The manual also suggests BSS may be ideal for macro close-up shots at ranges less than 1’ 8" (52cm). But engaging the self timer to minimize shutter release shake will disable BSS since the self-timer will only take one shot. So you have to make a choice: Use BSS and risk shutter release shake or engage the self-time and disable BSS. Nikon does not include a remote shutter release so you have to use the shutter release on the camera. As stated on page 113 of the manual, BSS will only work in Single shooting mode and will be disabled when noise reduction is set to Clear Image ModeTM. Selecting BSS also disables the flash since the flash cannot fire 10 time consecutively in the given time. Typically, you would not use BSS when taking flash shots since the flash will effectively freezes most motion blur. BSS is not recommended for moving subjects.

The Nikon BSS feature is most useful in diminishing blur due to camera shake.

In-Camera Red-Eye Fix Says Goodbye to Red Eye
Beyond faces, most Nikon Coolpix cameras can automatically detect and remove red-eye directly within the camera with Nikon's exclusive In-Camera Red-Eye Fix™ technology. This elegant solution to common red-eye pictures detects and corrects red eyes in most typical situations without the need to press buttons or select and highlight the eyes in playback. Nikon's red-eye solution is completely transparent to the user and the result is simple - less red-eye photographs straight from the camera.

D-Lighting Addresses and Eliminates Dark Photos
Tricky lighting situations or insufficient flash can sometimes lead to dark photographs. Nikon's new D-Lighting function is a tool to fix problems that occur with excessive backlighting and underexposed images from affecting the quality of the resulting pictures. D-Lighting, selected in Playback, automatically compensates for insufficient flash or excessive back lighting in order to obtain a balanced exposure throughout the frame. After applying D-Lighting, the camera saves the original image and a corrected copy to the camera's internal or removable memory. An application of D-Lighting can literally turn a dark, throwaway shot into a frame-able memory.
