Auto Lighting Optimizer and Live View

With Auto Lighting Optimizer (ALO) set to anything other than its disable setting, the Live View image on your EOS DSLR may appear bright even if manual exposure, exposure compensation, or flash exposure compensation has been set to record the image darker. If this is the case you should just turn off Auto Lighting Optimizer for Live View shooting. You can add ALO to captured RAW images later by using the Canon Digital Photo Professional software programme.
