This is a pet peeve of mine.
When someone talks about "Fine Art Photography" they seem, usually, to mean decor. Technically decor is covered by the term Fine Art, so it's not actually wrong, but for some reason it still rubs me the wrong way. Is your giant landscape in the approved primary color palette with a splash of complementary color so it will go in with the expensively designed living room really all that Fine? It's not like it says anything about anything, it's just pretty.
I don't object to pretty. If people who were doing serious Art also called their photographs Fine Art, perhaps I wouldn't be irritated. Artists generally don't, as far as I can tell. Fine Art is reserved for expensive decor, usually big.
Art is something else entirely.
