• , : Camera ready to take third shot.
During ADL bracketing, the amount of Active D-Lighting that will
be used with the next shot is underlined in the information display.
[] Disabling Bracketing
To disable bracketing and resume normal shooting, select OFF in Step 4 on the previous
page. To cancel bracketing before all frames have been recorded, rotate the mode dial to a
setting other than P,S,A, or U.
[] Exposure Bracketing
The camera modifies exposure by varying shutter speed and aperture (mode P), aperture
(mode S), or shutter speed (modes A and M). If auto ISO sensitivity control is enabled in
modes P,S,and A, the camera will automatically vary ISO sensitivity for optimum exposure
when the limits of the camera exposure system are exceeded; in mode M, the camera will first
use auto ISO sensitivity control to bring exposure as close as possible to the optimum and
then bracket this exposure by varying shutter speed.
