It is the business of the professional to get a good enough shot as efficiently as possible. "good enough" in this case is generally pretty good, this is not a low bar here.
That said, you can almost always do better if you have a chance to re-shoot. It's rare that my work does not improve, pretty much endlessly, if I have the will and ability to re-shoot with purpose. This is an advantage, in a sense, that the amateur has over the professional. The professional must do fine work on a schedule. The amateur, being unpaid, has no schedule and is free to do the best possible work on no schedule at all.
There's a difference between:
- producing a good shot of whatever it is (this might be what the poll is about) and that should be one exposure only, or go back to practicing
- producing the best possible shot of whatever it is, and that is arguably an unending process, as long as your patience and whatever it is are available
I generally get a decent version in one exposure, if I have a clear notion of what I want. Searching for the image takes 1 through infinity shots, though, if I do not know what I want.
