Exposure bracketing is when you take a series of pictures that have slightly different aperture settings. One reason to do this is if you are not certain what the best exposure is going to be. Another might be if you want to create a HDR photograph. Most cameras have a way to do this automatically, or you can do it using exposure compensation, or by manually adjusting the exposure between photos. When doing this, you want to take a “baseline” image that is in the middle of the desired range. Then you take 1,2 or 3 images and increment the aperture by about 1/3 stop above and 1,2, or 3 images and increment the aperture by 1/3 stop each below. This gives you a range of 3,5 or 7 total images.
