q Evaluative Metering
This is the camera’s standard metering mode suited for most
subjects even under backlit conditions. After detecting the
main subject’s position, brightness, background, front and
back lighting, etc., the camera sets the proper exposure.
¡ During manual focusing, evaluative metering is based
on the center AF point.
¡ If the subject brightness and background light level are
very different (there is a strong backlight or spotlight),
use partial metering <w> instead.
w Partial Metering
Effective when the background is much brighter than the
subject due to backlighting, etc. Partial metering covers
about 9% of the viewfinder area at the center. The area
covered by partial metering is shown on the left.
e Centerweighted Average Metering
The metering is weighted at the center and then averaged
for the entire scene.
