Automatic Exposure Bracketing can be your best friend in tricky lighting conditions. Bracket your shots to photographer is what hedge your bets is to a gambler.
Automatic Exposure Bracketing (also referred to as auto-bracket on some cameras) is an automatic feature that many of today’s DSLR cameras have, with the purpose of capturing multiple photos of the same subject featuring different exposure settings. This is not to be confused with multiple exposure feature, where 2 or more exposures will be made on the SAME photo.
Automatic Exposure bracketing is commonly used when there are tricky lighting conditions, which can fool your DSLR camera’s sensor into under or over-exposing. Assuming that you do not have too much time to experiment with various settings for producing a perfect shot (like in travel photography) photo bracketing can help to ensure you still get the shot without enraging the rest of your travel group. Simply enable photo bracketing, define 3 (or more) photos spaced up by (+/- 1.0 EV or more – depending on the light), and fire away. Chances are, that at least one of the photos will be well exposed.
When you press shutter button, the camera will fire 3 (or more) shots, similar to the one you can see on the photo to the left. One of the shots will be using the measured (‘correct’) camera exposure setting, while one will be under-exposed (darker), and one will be over-exposed (lighter).
These 3 images provide your safety net when you are in a hurry to make the shot, and do not have the time to fine tune your camera settings. Not to mention, that a properly executed bracketed shot is an ideal material for a good HDR image.
