I've spent a few hours re-reading and looking over some Harry Callahan books today and this statement by him stood out for me-"I just don't know what makes a picture,really-the thing that makes it something unique,as far as I can understand.Just like one guy can write a sentence and it's beautiful and another guy can write it and it's dead.What that difference is I don't know.That's as far as I'm religious;I don't believe in any religion." Just a little food for thought on a Sunday afternoon!
