An old argument. The point, for historical accuracy, where photography became an art form (in my opinion) was when a French photographer inadverdantly exposed a negative accidentaly and finished developing it anyway. He was reviled and attacked as being Satanic. He was the first person in the history of human artstic expression to deliver a black sun. It was a turning point, to say the least. Death had arrived and demanded an audience. There was outrage, it was blasphemy...the Frenchman did escape with his life, but his career was sacrificed. He made a mistake, embraced it, refused to apoligize, and paid for it with his reputation. Science and art are closely related in this regard.
