bracketing

A still camera technique for ensuring correct exposure. To bracket manually, one picture is taken at the estimated exposure setting; another slightly underexposed and a third slightly overexposed. One of the three images typically looks better than the rest. Cameras may also feature automatic bracketing, which takes several different exposures one after the other. See HDR for photos.
