Centre-Weighted Metering
With approx. 75% of the meter's sensitivity concentrated on the
12mm-dia. circle in the viewfinder and approx. 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 pictures
off-centre portion, use the AE-L button (pp. 74-75).
p
Spot Metering
Nearly 100% of the meter's sensitivity is concentrated on the
3mm circle in the centre of the viewfinder. Use this meter for
really selective exposure control—achieving the best results
requires experience.
