Andy,

Bracketing is a means of taking consecutive shots of the same subject at different settings. The most common use of bracketing is when you take one or more (usually three) images at different exposure levels of the same scene and then combine the images in post production to acheive a balanced exposure.

Depending on your camera, you may have the ability to take three, five, seven or even more photos in a range of differing exposures. Combine this with continuous shooting mode (this works with a Canon DSLR) and the camera takes the correct amount of shots for as long as you hold the shutter release button down.

Bracketing can also be used with a combination of shots at different depths of field by adjusting your focus point. You would have to make sure you were in single shot mode so you can adjust your focus for each shot. Macro photography may be enhanced by using this technique and is referred to as Focus Stacking.
