Scene Recognition System

with the Face Detection System

First introduced on the D3 and D300 flagship cameras,

Nikon's breakthrough Scene Recognition System is also

featured in the D90. 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 Nikon's

new Face Detection System to render human faces with a

newfound sharpness and accuracy.

Improved autofocus performance

The D90 demonstrates amazing autofocus accuracy by utilizing

color and brightness information from its 420-pixel RGB

sensor. 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 subject's color and

brightness information to keep it in sharp focus as you change

the composition.

Sophisticated auto exposure

Nikon's 3D Color Matrix Metering II became one of the most

highly acclaimed metering systems by delivering consistently

well-balanced exposures — even in lighting conditions that

confuse other systems. Further extending its exposure

capability, Nikon's Scene Recognition System evaluates

each scene's highlights, delivering even more light metering

precision. Moreover, the D90 detects faces when using

Playback

face priority AF, giving you ideal exposures of your human

subjects.

Incredibly accurate auto white balance

Auto white balance combines with Nikon's 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 its onboard white balance database.

Even under mixed lighting or difficult light sources like mercury

vapor lights, the D90 calculates an ideal white balance for

remarkably faithful colors.

Playback zoom

Utilizing information from the new Face Detection System, the

D90 detects up to ten human faces during playback. Select one

face and the D90 zooms in for faster focus confirmation.

Versatile, practical 11-point AF system

Thanks to Multi-CAM 1000

autofocus module, the D90's

11-point AF system has fast

and precise autofocus coverage

across the frame with the most

sensitive AF sensor operating

from the center. In addition,

the D90 has versatile AF-area

modes to handle most shooting situations: Single-point AF

is recommended for stationary subjects, dynamic-area AF

for moving subjects, auto-area AF for spontaneous shooting

and 3D-tracking (11 points) AF for changing composition after

focusing on your subject.
