The database of 30,000 actual shots redefines the concept of exposure accuracy for 3D Color Matrix Metering II and the new Scene Recognition System
The database of 5,000 actual shots among the 20,000 images stored for Auto White Balance is utilized for characteristics extraction
An upper photograph:• Lens: AF-S NIKKOR 14-24mm f/2.8G ED • Image quality: 14-bit RAW (NEF) • Exposure: [A] mode, 1/50 second, f/5 • White balance: Auto • Sensitivity: ISO 1600 • Picture Control: Standard
A lower photograph:• Lens: AF-S VR Nikkor 300mm f/2.8G IF-ED • Image quality: 14-bit RAW (NEF) • Exposure: [M] mode, 1/640 second, f/2.8 • White balance: Auto • Sensitivity: ISO 6400 • Picture Control: Standard

Sophisticated 3D Color Matrix
II
Metering
Nikon's 3D Color Matrix Metering II has long
been praised by discerning professionals
for its accuracy. The system analyzes scene
conditions such as brightness, contrast,
selected AF area, color, subject-to-camera
distance and even the reflective quality of
a scene. Then it compares this with an in-
camera database containing information
from over 30,000 actual shots for incredible
precision. Combined with the Scene
Recognition System, 3D Color Matrix Metering
II is now even more sophisticated. The bright
areas of your image are pleasing and precise,
while intermediate tones also remain faithful
to the original scene, even when backlit,
under harsh frontal lighting or in other difficult
lighting conditions. In addition to producing
the best possible exposure regardless of the
file format, this advanced metering system
gives you more satisfying results, frequently
without the need for retouch or enhancement.

Auto White Balance for a broader
range of lighting situations
Nikon's Auto White Balance systems
have been praised for their accuracy, but
professional photographers and Nikon
engineers aren't easy to satisfy. Tricky lighting
Auto White Balance used for natural daylight
can fool the most "intelligent" of cameras
from time to time. For example, a camera
might interpret a meadow under the noonday
the scene, cross-referencing it with 5,000
sun and a table under fluorescent light as
actual shot data examples among the 20,000
similar subject matter. But now, when Nikon's
images stored in the camera. So no matter
