I shoot mostly BW LF. I don't bracket for this except rarely. Bracketing is a huge waste of time. Chances are the picture is a dud anyway, right? Really. In ten pictures, how many are keepers? Next, there is all that processing, loading holders, cleaning holders, proofing, indexing, and the rest. Then, if I do bracket a frame and then at the end of the day, I'm short a piece of film, I'm really pissed.

Don't bracket, get it right the first time and save that sheet of film for your 'moonrise'.
