This unique technology utilizes a 420-pixel RGB sensor to analyze immense amounts of scene and color information in order to understand what the camera is about to shoot.Milliseconds before the shutter is released, the camera optimizes the autofocus, auto exposure, i-TTL control and white balance.The D90 also uses Nikons new Face Detection System to render human faces with a newfound sharpness and accuracy.When shooting in Auto-area AF mode, the camera quickly focuses on the main subject by detecting foreground, background and subject position.
When using 3D-tracking (11 points) mode, the camera uses your subjects color and brightness information to keep it in sharp focus as you change the composition. Moreover, the D90 detects faces when using face priority AF, giving you ideal exposures of your human subjects. Even under mixed lighting or difficult light sources like mercury vapor lights, the D90 calculates an ideal white balance for remarkably faithful colors. Select one face and the D90 zooms in for faster focus confirmation. In addition, the D90 has versatile AF-area modes to handle most shooting situations. The center focus point can be switched from normal to wide according to the movement of the subject. ![]() Three contrast-detect AF modes let you focus on any point in the frame. A wide 170-degree viewing angle makes it easy to confirm focus after shooting or during Live View. Thats why Nikon subjected numerous D90 shutter mechanisms to grueling 100,000-cycle shutter-release tests with the unit fully assembled in the camera. Just turn the mode dial to the appropriate icon: Portrait, Landscape, Close-up, Sports or Night Portrait. Unlike traditional scene modes, the D90 will automatically optimize the exposure, image processing, Active D-Lighting, and Picture Control to get the most out of your subject matter. Whats more, the D90 has exceptional low-noise performance and accurately adjusts the camera settings whether VR (Vibration Reduction) is activated or not, so you can expect beautiful, crisp images, even in many low-light scenes. The built-in flash has an 18mm lens coverage and works as a wireless commander, controlling up to two independent groups of an unlimited number of remote Speedlights and providing incredible creative lighting control on location or in the studio.
