3D-RGB Matrix Metering II

This exclusive Nikon feature not only evaluates brightness and contrast

but also color. The results will astonish you. What once took

professional experience to determine is now literally at your fingertips.

Data from more than 30,000 actual scenes are stored in the camera's

database, with algorithms that are continually added. The RGB Color

Matrix Meter can even tell if tungsten or fluorescent lighting is in use.

Once the camera receives scene data, its powerful microcomputer and

database work together to provide unequaled exposure control. Nikon's

3D Color Matrix Metering II also uses special exposure-evaluation

algorithms optimized for digital imaging that detect highlight areas and

calculate appropriate exposures. It even gives proper exposure values

when shooting white subjects in cloudy conditions, a near-impossible

situation for most cameras.
