Exposure Compensation
Exposure compensation is used to alter exposure from the value suggested by the
camera, making pictures brighter or darker. It is most effective when used with
center-weighted or spot metering (pg. 87).
Exposure compensation is available in modes P, S, and A (in mode M, only the
exposure information shown in the electronic analog exposure display is affected;
shutter speed and aperture do not change).
Press the E button and rotate the main
command dial until the desired value is
displayed in the control panel. Exposure
compensation can be set to values
between –5 EV (underexposure) and
+5 EV (overexposure) in increments of
1 /
3
EV. In general, choose positive values
to make the subject brighter, negative
values to make it darker.
At values other than ±0, a E icon will be displayed in the control panel and
viewfinder after you release the E button. The current value for exposure
compensation will be displayed when the E button is pressed.
Normal exposure can be restored by setting exposure compensation to ±0. Exposure
compensation is not reset when the camera is turned off.
