Nikon D300 User Manual page 701

have 23 pictures on the card. Three pictures in one shutter
press!
Be sure to set your D300(S) back to normal bracketing in
Custom setting e5 when you're done, unless you use WB
bracketing frequently.
My Recommendation: Personally, I prefer to shoot in NEF
(RAW) mode and make minor or major WB adjustments in
the computer post-processing stage of the image's
preparation. However, others want to use WB bracketing or
Nikon wouldn't have given it to us.
