Art and Photography

Looking at Aaron Scharf's "Art and Photography"  the other day I thought. Is that it? It seems to me that the influence of photography on art is insignificant. The influence is all the other way. Writing about the Durieu photos which Delacroix owned is just a footnote to art history.  As Sickert wisely said.The only artists who should use photographs are those who have no need of them. In other words use photographs as an aide-memoire if you wish.
