When people ask me what I do I have several choices. I can just tell them I'm a photographer. But they never seem satisfied with that and ask if I shoot weddings, etc. I have replied by saying that I'm a "landscape photographer" and then people ask me if there's a good living to be made in photographing gardens. So out of the desire not to call myself an "art photographer" or "fine art photographer" I tell them a far more detailed and lengthy description of what I do. Like," I travel around and shoot B&W photos of landscapes and scenes and then make prints which get sold in galleries" which still sounds pretentious and then they ask me if I own the galleries. I guess if I did they could then generalize me as a "gallery owner".
Simple fact of the matter is that if you make your living by selling prints or "art" that no matter what you say, short of not saying anything, it's bound to sound pretentious to someone. Using the term "art photographer" doesn't work well either because most people seem to think that anything to do with art is BS or that it's just a hobby of mine. I guess I'm stuck with the long answer.
