224 Shooting Settings
Bracketing automatically varies exposure, flash level, Active
D-Lighting (ADL), or white balance slightly with each shot,
“bracketing” the current value. Choose in situations in which
getting the right settings is difficult and there is not time to
check results and adjust settings with each shot, or to
experiment with different settings for the same subject.
• Bracketing is available in modes P , S , A , and M only.
