Everybody considers himself a genius post-processor, but damned few are competent photographers. You can second-guess any photograph you see. I can nit-pick HCB's and Ansel's stuff too, but that kind of nit-picking hasn't anything to do with reality. As Seamus says, almost always the first shot -- the view that made you lift the camera -- is the right one. What's more, there are very few situations where a picture contains enough information about what might be beyond the frame to warrant a recommendation for a change of point of view. Sometimes a suggestion about post-processing actually can improve a picture, but even then, on LuLa you're basing your suggestion on a small, compressed JPEG. Most people haven't a clue whether or not or how post-processing can improve a picture. Slobodan's one of the few who has a clue (though we often disagree), and there are a couple others here who understand enough to make a reasonable, if not always correct recommendation. But most of what passes for constructive criticism here is, in fact, nit-picking.
