After getting back some chromes sent away for processing I had a few where I somehow grossly misjudged my exposure. This got me to thinking about how to improve upon this. Of course I shall first review what I had done, what I metered and try to learn from my mistakes. But sometimes even when you think you have it right you may be sometimes slightly off so when circumstances allow it would be nice to proof the image. I don't have a poloroid back but since I was thinking of replacing my broken down old cannon 35 mm camera with a digital one I was wondering if this could be an effective way to proof a scene like a polaroid does. Can this be done with a digital camera say something like a Canon EOS 30d? Looking at the LCD screen on these cameras can help one judge a composition but can it aid you in judging a proper exposure or am I hoping for too much from such a camera? Anyone out there tried it? If so has it been successful for you and what is your set up? Thanks in advance.
