I've never taken any classes, and only ever bought one book. The day after I got my camera I picked up Understanding Exposure by Bryan Peterson.
He has some very helpful videos on youtube and his own channel that is pretty helpful. For me just getting out there and shooting is the best way to learn but Peterson is always got some good videos and his excitement about photography is fun. When I think of a real photographer I think of this guy. Someone creative who sees shots in fun interesting places, not baby photography.
