Yes, Joe is right. We have had students from all over Europe, Canada and the US. One was from Asia but was living in the US at the time, so we have had none from OZ or NZ yet, nor from Japan or China.
And no, there are no courses like this anywhere else AFAIK. We try to bring in some Kodak retirees to address your questions and supply additional information. You might call it "lunch with the experts", as some of the attendees have been Bob Shanebrook and Paul Gilman among others.
Joe, IDK, but I would guess the next one in the fall. Mark and I have to plan it out. The level 2 emulsions take longer to make so the course will probably be a day longer.
