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.
