The following table explains the settings in more detail:
If the new setting is anything other than the default Center-
Weighted setting, the icon for the setting (in the previous table)
will appear in the Live View screen.
The new setting remains in effect until it is changed again or
until the camera is turned off. The AE Metering setting resets to
the default Center-Weighted setting when you turn the camera
off. Holding down the Menu/OK button when you turn the
camera back on will restore this setting to what it was when
you turned it off.
Setting Description
Average The camera uses the entire scene region to measure
and calculate exposure. Use this setting when you
want everything in the picture to be used equally when
calculating exposure.
Center-
Weighted
The camera uses a large area in the center of the
scene region to measure and calculate exposure. This
setting is good to use when the subject of the picture is
in the center of the frame. Exposure will be based
more on the subject than on its surroundings. This is
the default setting.
Spot The camera uses a small area in the center of the
scene region to measure and calculate exposure. This
can be useful in backlit scenes or when the subject of
the picture is very dark or light compared to the rest of
the scene. When using this setting, frame the subject of
the picture in the center of the focus brackets, then
press the Shutter button halfway down to lock the
exposure and focus on the spot in the center. Then
recompose the scene as desired and press the Shutter
button all the way down. NOTE: When this setting is
used, parts of the image can end up over or under-
exposed.
