This photo turned up on a page of “Iconic Rock n Roll Portraits” by photographer Bob Gruen, who became famous for photographing rock musicians, such as the famous shot of Led Zeppelin standing next to their Boeing 720. But aside from the subject matter, why isn’t this portrait of Bob Dylan just a bad photo? Is there anything about its execution, or the result of its execution, that warrants its being called “iconic?” I’m not being cheeky; I think it’s an honest question that is worth discussing.
