Bill, I don’t think of myself in terms of amateur and professional because I’m mostly doing photography as art and expression. And, no, I don’t do a lot of chimping and trial and error unless I’m specifically trying to work out an issue. When I’m actually shooting, I shoot, and try to use my experience, knowledge, and gut to guide me rather than my LCD screen. I’m fine with seeing the results when I get home. If I missed something . . . well . . . tomorrow is another day.
I was using “amateur” to mean a person not very interested in photography per se, but rather interested in getting decent pics of his kids or tourist attractions.
