At what point do you become and Artist rather than a photographer or maybe a fine art photographer rather than a photographer?

I ask because I see so many web sites where people call themselves "Fine Art Photographers" but when I look at the work on show I see largely "landscape photography", "documentary photography" and also what I think is really "photo journalism" or "Photo Essay". Rarely do I see what I would consider art photos with the exception of a smattering of abstracts.

Why don't these photographers call themselves Lanscape Photographers or Documentary Photographers or Photo Journalists or Photo Essayist? Why do they wan't to label themselves Artists? Is it just because everyone else does? Is it because they think calling themselves Artist makes their work more valuable? Is it ego? Or is it just my perception of what an Artist is or does is different from these photographers.
