Find how many bracketed exposures cover a scene's dynamic range.
A bracketed set centers a base exposure and steps above and below it, so the number of frames depends on the scene range divided by the step. High-contrast scenes exceed a sensor's range, and bracketing lets you merge or choose frames that hold both highlights and shadows.
Exposure Bracketing
Brackets = ceil(scene range / stops per bracket) + 1
