Mainly self taught. Playing around and learning the relations between aperture and shutter speeds on my own, burning through some film. In college, I did take a few photography courses, which focused mainly on digital, so as I continued on with film it was more by teaching myself. Though with those college courses, I had access to a nice darkroom which my instructor helped me with and I just experimented as I always have with my photography. Otherwise, being the only film shooter in my classes, I had the freedom to go my own way and learn, as I continue to do so!
