One thing I learned during today's class. I hate my Linhof to Deardorff adapter board! Everything is wonky, shaky and fragile. I will buy a new solid one piece Copal 1 lens board to use in Asia. I want something strong and durable. That last thing you need to worry about when shooting large format 8x10 portraits is shitty lens boards. Everything needs to flow smooth and easy, and that includes a good solid well made lens board.
