A friend of mine just got a Canon 20D. I've had mine for awhile and am pretty familiar with all the settings. She asked me if you can shoot with the LCD screen on to frame your shots instead of using the viewfinder. I've never had the desire to do so and I just figured you couldn't. I went through my manual and the camera menu but didn't find anything about this (I was skimming with the manual though). Is it possible to do so?
