Exposure Compensation

Another great feature of all modern DSLRs, is the ability to control the exposure by using the “exposure compensation” feature. Except for manual mode, exposure compensation works great for all camera modes. Whether you are shooting in Aperture Priority, Shutter Priority or Auto/Program modes, dialing the exposure compensation up or down (plus to minus) will allow you to regulate the exposure and override the camera-guessed settings. If you find your image (or parts of your image) underexposed or overexposed, you can use exposure compensation to adjust the exposure without manually changing the aperture or shutter speed.
