How Automatic Exposure Bracketing (AEB) Works?

2 Flares 2 Flares ×

If you find yourself in a situation where you’re not sure what type of exposure to go with and you don’t have time to test a few shots, check your digital camera to see if it has an Automatic Exposure Bracketing feature, generally known as AEB.

If you choose the AEB option you can typically take three quick photos at three different exposures. In theory, one of these shots should be the right exposure according to the camera’s internal meter, one shot will be underexposed and the other will be slightly overexposed. You basically get three images that are the same except for the exposures. This allows you to choose the one you like best.

It’s a good idea to learn how to use this feature and how to set and change the variation in exposures. For instance, you may want the three photos to be relatively close or you might want a wider variance between the three exposures, where there’s a large difference between the under and overexposed shots.

You can use the AEB feature in both Aperture Priority Mode and Shutter Priority Mode. If you use it in Aperture Priority you can select the aperture that you want to use and the camera will take the photos by varying the shutter speed. If you use the AEB mode in the shutter priority then you can choose the shutter speed and the camera will vary the exposures by changing the aperture in the photos.
