CENTER-WEIGHTED METERING

SPOT METERING

With 75% of the meter'ssensitivity concentrated on the 12mm- dia. circle in the viewfinder and 25% outside this circle, this meter becomes useful in situations where you want to base exposure on a specific area in the scene. In the auto exposure mode, to measure the brightness of the picture's off-center portion, use the camera'sAE-L lever (pp. 88-89).

Nearly 100% of the meter'ssensitivity is concentrated on the 3mm circle in the center of the viewfinder. Use this meter for really selective exposure control-achieving the best results requires experience.
