What is the benefit of shooting in Manual mode instead of Shutter Priority or Aperture Priority? If all you do in Manual is match the shutter speed to the aperture to get a "correct" exposure, why not choose one and let the camera automatically match the other to it? I tried shooting in Manual yesterday and while I was diligent about dialing in "correct" exposures, the results just didn't measure up to when I use Aperture Priority mode. Maybe this is because I was paying more attention to the camera dials than to the composition of my photos. But I am wondering whether the camera is simply more accurate at matching shutter speed to aperture than I am when doing it by hand. So, why go Manual? And what can I do to improve my results in Manual mode?
