Setting Up Auto Bracketing

Select your camera’s auto exposure bracketing (AEB) function. This is commonly assigned to either a ‘BKT’ or ‘ AEB’ button, but is also found in the menus, either as a standalone item or in the sub-menu for drive modes.

Set the order or sequencing to ‘Under>Metered Value>Over’ and choose a five-frame sequence with an exposure value (EV) of one stop between each frame. If your camera only allows you to shoot three frames in an auto bracketing sequence then do this with a +/-2.0 EV adjustment for the underexposed and overexposed frames.

Set your drive mode to its high speed setting and now, when you press and hold the shutter, you’ll take five shots in quick succession.

The first will be underexposed by two stops to capture all the highlight detail, the second will be a little brighter, the third will actually be at the regular exposure settings, the fourth will be brighter still, and the fifth will be over exposed by two stops to record detail in the very darkest parts of the frame.
