The f-100 has a custom feature (as does the f-5, I think) where you can set the bracketing to be either flash or exposure, as opposed to the usual setting where both are set. Well, I guess with flash bracketing only, the exposure would stay the same, but the intensity of the flash would vary (e.g...so the dof would stay the same, if that's what you want), but: 1. when would you want the flash to remain the same but the exposure change, and 2. What happens in the usual setting when both flash and exp. bracketing are set together, and why wouldn't you always want this on?
