Evaluative metering
This is suited for most picture-taking
situations including backlit conditions.
The subject's position and brightness,
the background, the existing light,
backlight conditions, and the active
focusing points are taken into account
to obtain a suitable exposure.
Partial metering
The exposure setting is based on the
brightness of an area 9.5% of the
viewfinder screen at the center. It is
effective for backlit subjects.
• The partial metering area (shaded) is
approximated by the diagram on the
left.
Centerweighted averaging
metering
The metering is weighted at the center
and then averaged for the entire
scene.
