This page summarizes a set of resources that disseminate art or art education; not exclusively in the medium of photography.
A currated photography gallery web site where published photographs have been highly scrutinized and critiqued by peer photographers at different (but often high) skill levels. 1x is a source of photography at a high level.
A photography gallery web site where published photographs are viewed by and up-voted by fellow photographers. A more "populist" site than 1x but equally a home to high quality photography.
A good source of news and articles about photography, cameras, lenses, technique and the art of photography.
B&H Event Space
A series of inspirational and educational talks from photographers.
