Like many professional-level digital SLRs, the Nikon D300 includes automatic exposure bracketing. Using this feature, you can take three or more consecutive shots with a different exposure for each. Auto bracketing originated with film cameras as a means of assuring at least one good exposure for each shot. Although digital cameras provide you with immediate feedback about image quality, auto bracketing helps you create high dynamic range images, built from multiple exposures merged in photo editing software.
Select Menu then choose Custom Setting E5. Choose flash or exposure bracketing by selecting AE & Flash to change both exposure and the flash level; AE Only to vary only the exposure; or Flash Only to change only the flash level.
Press the Fnbutton and rotate the command dial to select the number of bracketing sequence shots. The Nikon D300 allows you to choose up to nine shots in your sequence.
Press Fn again, then rotate the sub-command dial located beneath the Power button to select your exposure increment. The settings default to 1/3, 2/3 and 1 exposure value (EV).
Press the shutter-release button once for each exposure increment. For example, if you chose a three-shot bracketing sequence, press the button three times. The camera will automatically adjust the exposure for each shot.
Use a tripod and a remote shutter trigger to frame each shot exactly the same.
To cancel auto bracketing, press the Fn button and rotate the main command dial until the bracketing sequence number reads 0.
