I feel like I'm all over the place style-wise, though of course I've still got a lot to learn. I've never had any training, formal or informal. I learned everything about photography and lighting from playing at home and reading. I light entirely by instinct right now. Also I believe my interaction with the subject while shooting is improving. I'm such a quiet person normally, but I can't silently photograph someone, that would be just bad. :)
I'm open to assisting for good photographers to learn, but the ones I've contacted either fell through or they just never got back to me. Should I take the CSCC photo course? They have lighting classes. I think I'm improving with each shoot but I don't get much feedback, maybe a class would help... then again it could hurt as well.
