In this picture of Montmartre, I was just testing a new lens for a special effect. When I went to America, I left most of my material in Paris, and when I returned I found sixty percent of the glass-plate negatives were broken. This one I saved, but it had a hole in it. I printed it anyways. And accident helped me to produce a beautiful effect.
