Hi, I'm interested in finding a website with a collection of many of the famous photographers work, so I can really start to consider why I like some photos and not others. The point is to get better at composition and understanding composition. I've realized photography is about the art, not the science. I need to start learning about design elements, composition, etc. by studying great and successful photographers. I'd rather not buy a book right now, but rather online gallery's featuring famous photogs work.
