David sent me an article on Magnum's blog with thoughts and suggestions about photography from several Magnum photographers.
Sometimes, one photographer's advice to look at other photographer's work, is contradicted by another who prefers to not be influenced by others; I suppose it's up to each of us to decide.
I liked Constantine Manos' advice, "... show us something we have never seen before and will never see again." I would like to think that the "Fantastic Foursome" photograph, above, was inspired by this philosophy.
