If you can afford to do it and live in a metropolitan area, one of the best ways to learn is to get a job as an assistant in a good commercial studio. You'll spend 8 hours or more a day working in photography for miserable wages, but what one can learn is priceless. I took this route many years ago and kept a journal of every shot I worked on. As a matter of fact, one of the photographers I worked with is now a professor at RIT and a colleague of Andy's, Howard LeVant. Fred Gibbons
