I'm self taught in that I received no formal training or education regarding the artistic or technical aspects of photography, however over the years I have had various mentors, attended a few conferences and workshops, and attempted to mimic certain things I was interested in, etc.

Part of any education involves exposure to the field of endeavor, so in that manner, I have received information and guidance from others. I don't believe there really is an opportunity to be self taught, unless you somehow invent and develop something from the ground up.
