3D Color Matrix Metering
From Nikonians Wiki
Matrix metering splits an scene into multiple segments to determine the best possible exposure by evaluating either 420-segments or 1,005 segments, depending on the Nikon DSLR model.
This metering system was introduced with the Nikon F5 and the 1005 pixels RGB Metering Sensor reads both the scene's color as well as its brightness and contrast. Its RGB filters evaluate the color information and can metering from EV 0 to 20 (at ISO 100 with an f/1.4 lens).
3D Color Matrix Meter II goes further by taking into account
- the scene's contrast and brightness,
- the subject's distance (with a D- or G-type NIKKOR lens),
- the color of the subject within the scene and
- the RGB color values in every section of the scene.
But that is not all, 3D Color Matrix Metering II also uses special exposure-evaluation algorithms, optimized for digital imaging, to detect highlight areas. The meter then accesses a database of over 30,000 actual images to determine the best exposure for the scene. Once the camera receives the scene data, its powerful microcomputer and the database instantly work together to provide the finest automatic exposure control available.
It has meanwhile been replaced by 3D Color Matrix Meter III
