The workshop was great. Joe teaches in very much the same way he writes. So if you've read any of his books, you'll know what to expect. He doesn't hold anything back and pretty much everything he says is useful information in one way or another. Speaking of books, I've been reading his newest - Sketching Light - and it is great. Filled with dozens of examples of real shoots Joe has done, including all the lighting info, camera setting, problems encountered and solutions uses. Well worth the $50 if you are into lighting and want to step up your game.
