Physics of Photography. First college course I took at the UofU (in the physics and astronomy department, not the art department). Physics, maths, optics, chemistry, mechanical engineering, technology and industry, applications, and the history of of these things in photography, and the history of photography as an art and as a science and a technology. Blew my tiny teenage mind. I had more pounded into my wee little brain in that quarter than any other period before or since. The teacher was awesome. Lot's of dark room time, lots of toys, lots of hands on science labs. I got a C, and holy shit I worked my ass off for it. Best course EVER!
