The most common type of autobracketing used is exposure autobracketing or Automatic Exposure Bracketing (AEB). Using AEB, the camera is set to capture the same image several times with slightly different exposures, both over-exposed and under-exposed (lighter and darker) compared to your current exposure setting on the camera. Depending on make and model of your camera, the difference between each of the autobracketed shots could be anywhere up to two stops in each direction, in half-stop or one-third stop increments.
Each DSLR has a different way of selecting AEB, Nikon’s D70 has an accessible button on the back marked BKT while other DSLRs like Canon have an AEB setting in their menus.
Another common form of autobracketing is white balance autobracketing. This technique applies only to DSLRs, not to film cameras. This setting causes the DSLR to capture the same image several times and slightly changing the white balance settings, with both higher and lower color temperatures compared to the current setting on the camera.
