I was in Boston a couple weeks ago for the Flashbus event with Joe McNally and David Hobby. While I haven't ventured into the world of off camera flash just yet, which was really the focus of the event, it was still a great learning experience. David did his presentation in the morning and Joe did his thing in the afternoon. Both of them were so friendly and casual and all about questions from the audience..I really learned alot. For Joe's part, he was working live without net getting people from the audience up on stage and taking pix. We sat there and watched him shoot and tweak and shoot and bend and a gel on this one, softbox here, reflector there...it was really cool to watch him work...took a lot of the mystery out of it. Those guys aren't hung up on numbers, they take a guess (yeah, albeit an experienced guess), take a shot, take a look, make some adjustments and keep going. So cool to hear them talk about light...I can't remember any of the sage bits right now..but just the deep felt appreciation for light.
