How to use auto exposure bracketing (AEB) on the EOS 1Dx Mark III.


Auto Exposure Bracketing (AEB)

Auto Exposure Bracketing (AEB)

In exposure bracketing, three consecutive images are captured at different exposures within your specified range of up to ±3 stops (in 1/3-stop increments) by automatically adjusting the shutter speed or aperture value. This is called AEB.

AEB stands for Auto Exposure Bracketing.

  1. Press the MODE and Drive mode/AF operation button simultaneously (Timer 06sec).

    • AEB setting and 0.0 appear on the top LCD panel.
  2. Set the AEB range.

    (1) AEB amount

    (2) AEB range

    • Turn the Main Dial or Quick Control Dial dial to set the AEB range.
  3. Take the picture.

    Standard exposure

    Decreased exposure

    Increased exposure

    • Three bracketed shots are taken, according to the specified drive mode, in this sequence: Standard exposure, decreased exposure, and increased exposure.
    • AEB will not be automatically canceled. To cancel AEB, follow step 2 to set the AEB amount to “0.0.”


  • During AEB shooting, the AE lock icon in the viewfinder and the AEB setting icon on the top LCD panel blink.
  • If the drive mode is set to Single shooting/Silent single shooting, press the shutter button three times for each shot.

    In High-speed continuous shooting/Continuous shooting/Low-speed continuous shooting/Soft continuous shooting/Soft low speed continuous modes, holding down the shutter button completely captures three images, one after another, before the camera automatically stops shooting. When 10 sec. self-timer or 2 sec. self-timer is set, three consecutive shots are captured after a delay of approx. 10 or 2 sec.

  • You can set AEB in combination with exposure compensation.
  • Ends of the exposure level indicator are displayed as Right end of the exposure level indicator/Top end of the exposure level indicator or Left end of the exposure level indicator/Bottom end of the exposure level indicator when the AEB range exceeds ±3 stops.
  • AEB is not available in flash photography or bulb exposures.
  • AEB will be canceled automatically if you do any of the following: Setting the power switch to Power off or when the flash is fully charged.
