As an artist, I am interested in the history of Art, and I have a small collection of books on Art and Art History. Knowing all this stuff doesn't make me a better artist, it just helps me connect with and understand the Art of those who have come before.
There's a discussion that comes to the fore in one of my books about Art History - it is, in fact, a textbook from some time ago. In it, the idea is proposed that the difference between Art and Craft is originality.
Not to get into a monolog about the differences and the similarities - but I would offer up a question: If I paint 16 portraits that all look alike, are they Art, or Craft?
And if I create an highly original photograph and then print it 16 times, are they Art or Craft?
In many ways it's just a question of semantics and it has little to do with one's worth as an artist - except that those of us whose Art includes photography have a difficult time, at times, convincing consumers of Art that photographs ARE Art.
And, by the way, they are.
