q Evaluative metering
This is an all-around metering mode suited for
portraits and even backlit subjects. The camera
sets the exposure automatically to suit the
scene.
w Partial metering
Effective when the background is much brighter
than the subject due to backlighting, etc. The
gray area in the left figure is where the
brightness is metered to obtain the standard
exposure.
e Center-weighted average metering
The brightness is metered at the center and
then averaged for the entire scene. This
metering mode is for advanced users.
q Changing the Metering ModeN
With q, the exposure setting will be locked when you press the shutter
button halfway and focus is achieved. With w and e, the exposure setting
is set at the moment of exposure. (The exposure setting is not locked when
you press the shutter button halfway.)
