A
Exposure Mode M
In exposure mode M, exposure compensation affects only the exposure
indicator; shutter speed and aperture do not change.
A
Using a Flash
When a flash is used, exposure compensation affects both flash level
and exposure, altering the brightness of both the main subject and the
background. Custom Setting e3 (Exposure comp. for flash, 0 342) can
be used to restrict the effects of exposure compensation to the
background only.
