I've never considered myself an "artist". Just "photographer", and lately, not even that.
It's something of a stigma that I've internalized growing up. It might be my working class upbringing, growing up in a military family, that always associated "ART" and artists as elitist, superficial, pretentious, etc.
I personally don't think that about "art" and the "artists" I know, film-makers, painters, actors, graphic designers, etc., who also seem hesitant about referring to themselves as artists, but might if it means making a buck and presenting themselves a certain way to client$.
I've had other people call me an artist, that's OK...whatever, I've been called worse ;-), but I personally don't refer to myself as one.
