Thanks for the kind words, Dan.
I'll tell you my thoughts on classes (I have had a photography class, BTW, when I was in film school. Taught by Cora Wright Kennedy). I think the value of a class is basic technical skills: how to make a good exposure, what different lenses do, how light behaves, that kind of thing. Once a person understands those things, on a second nature level, then the next step is to learn composition. And, honestly, I don't think composition can be taught. Maybe at a very basic level. I was surprised, when I was putting together one of my photo classes, how little training/teaching there is about composition, how little it taught, and how much what was there contradicted itself and other training on the same topic.
Ultimately, I think composition skill is either a) something you're born with, b) something you learn through trial and error experimentation, or c) something you never get, but not something that's imparted by knowledge transfer. I'd love to hear yours, or anyone else's, thoughts on that.
