My feelings about photography are best expressed in the sentiments of Minor White:
"We emphasized the creativeness that happens at the moment of seeing over the kind that takes place in the darkroom"
This was White's approach to teaching photography at the California School of Fine Arts. Learning to 'see' was more important than any technical skill. This philosophy was practiced by White and is reflected in his seminal work "Rites and Passages"
I prefer to edit as much as possible while looking through the viewfinder before I release the shutter. I prefer prime lenses to zooms because I believe they teach a more disciplined approach to the art of photography. I try to treat each exposure as if there is no computer waiting to correct my errors: no second chance to alter the framing or the exposure.
Spend time composing your shot; look carefully at the corners of the frame, check depth-of-field, consider the exposure and be satisfied with your composition. Yes, post-processing is part of the photographic process and is an important step. Just as the darkroom is to a photographer that uses film, we use it to complete the creative flow to a finished work.
However, I believe many digital artists have come to rely on the computer to such a degree that it has replaced an understanding of how to manipulate the camera; camera technique if you will. The computer is relied upon as the means to compose the frame and determine exposure-- things the camera should be used for. 'See' the finished work with the camera, polish it lightly with the computer.
