#Bracketing

bracketing

Bracketing is the practice of taking multiple variations of the same shot with a changing factor. Differences between frames can include varying ISO, aperture, shutter speed, focus, flash, and white balance to name a few. Purposes for bracketing include capturing multiple shots to safeguard against missing a correct exposure or white balance, capture multiple frames with different focal points for focus stacking in post production, and probably most commonly, bracketing exposure for blending into HDR photography. Bracketing can be done manually, and many cameras can do multiple different types of automatic bracketing.
