Is Auto Exposure Bracketing (AEB) The Same As HDR?
AEB is auto exposure bracketing, an image capture technique in which more than one photo is taken of the same thing using different exposures.
HDR is High Dynamic Range. High Dynamic Range is the range of tones in an image.
So, whilst the two are not the same, you can use AEB to create HDR images. However, you can also create HDR images in a single image capture using software without AEB.

What Is Auto Exposure Bracketing (AEB)?
Auto exposure bracketing is the process of taking multiple photos at the same time to capture a wider dynamic range, a wider range of lights and darks. More of what we can see with our eyes.
When using auto exposure bracketing the camera automatically takes three photos, one the correct exposure, one underexposed photo, and one overexposed photo. The amount of under and over-exposure is set by the photographer.
The camera changes the aperture or shutter speed for the under and overexposed photos, which is determined by the picture mode that is being used.
Auto exposure bracketing is also known as AEB and is defined as an advanced operation by Canon.
