Fine art is a term most likely very few understand. Here are two dictionary definitions: “art” is the expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture, producing works to be appreciated primarily for their beauty or emotional power; “fine art” is creative art, especially visual art, whose products are to be appreciated primarily or solely for their imaginative, aesthetic [meaning ‘beauty’], or intellectual content.
So the dictionary experts went around in a circle. The key seems to be in the word “solely” — fine art exists for its own sake, whereas art can be produced for any number of reasons. Does the stock image photographer produce art or fine art?
I doubt this fits in either category, but I was fascinated with the play of light and shadow.
