Call me stupid, but I've never been able to really understand what street photography means. Is it random pictures of strangers? Urban pictures? People living their daily lives? What defines a good photo in that category? For example, a good wildlife photo is one that shows an up close view of an animal in it's environment, a good landscape photo brings out the beauty of a landscape with an attempt to make it look grand and dramatic. What sort of general criteria is there for street photography since it's all the hype now
