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
l
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
l
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.
3D Color Matrix Metering II delivers consistently well-balanced exposures.
Incredibly accurate auto white balance
l
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
l
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.
