Metering Methods
Your camera has three metering methods: evaluative metering, partial
metering, and centerweighted averaging. The camera normally uses
evaluation metering, but automatically changes to partial metering when
you use the AE lock function, and changes to center-weighted averaging in
M (manual exposure) mode.
Evaluative Metering
Used for all general situations,
including backlighting. The camera
provides the proper exposure for the
main subject at all times by using the
three focusing points to determine the
subject's position in the viewfinder, as
well as the brightness, background,
and front- or backlighting conditions.
Partial Metering
Measures the brightness in the central
area that makes up approximately
6.5% of the viewfinder. This is
particularly effective in backlit
conditions, when the area around the
subject is brightly lit.
*The illustration at left shows the
partial metering range.
Centerweighted Averaging
Metering
Measures the overall average
brightness of the image in the
viewfinder frame, with emphasis on
the center area.
fl «In one-shot and Al focusing modes (except Al servo mode), when you press
the shutter button halfway, the camera automatically applies the AE lock as
soon as it has focused on the subject.
*You cannot select or change the metering method.
