Nikon D300 User Manual (en)

The D300 offers three types of bracketing: exposure bracketing, 
flash bracketing, and white balance bracketing. In exposure 
 (pg. 117), the camera varies exposure compensation 
with each shot, while in the case of flash bracketing (pg. 117), flash 
level is varied with each shot (i-TTL and, in the case of the SB-900 
and SB-800, auto aperture flash control modes only; see pages 
357–360). Only one photograph is produced each time the shutter 
is released, meaning that several shots are required to complete 
the bracketing sequence. Exposure and flash bracketing are 
recommended in situations in which it is difficult to set exposure 
and there is not enough time to check results and adjust settings 
with each shot.
In white balance bracketing (pg. 121), the camera creates multiple 
images each time the shutter is released, each with a different 
white balance adjustment. Only one shot is required to complete 
the bracketing sequence. White balance bracketing is 
recommended when shooting under mixed lighting or 
experimenting with different white balance settings.

At default settings, the camera varies both exposure and flash level. 
Custom Setting e5 ([Auto bracketing set], pg. 297) is used to choose the 
type of bracketing performed.
Changes to bracketing settings can be made using the Fn button (the 
default setting, see Custom Setting f4, [Assign FUNC. button], pg. 302), the 
depth-of-field preview button (Custom setting f5, [Assign preview 
button]), pg. 305), or the AE-L/AF-L button (Custom Setting f6, [Assign AE-L/
AF-L button], pg. 306). Note that some “button press” options can not be 
combined with options using “+dials.” The explanation that follows 
assumes that bracketing is assigned to the Fn button.
