you are right Regular Rod, I will never forget the first 8x10 ektachrome I've seen in the 80's, or the incredible look through a 8x10 screen in this times....
I don't want to stop him, I think it is a good idea to go to analog and to large format, but 8x10 film is little bit expensive in my mind if you start and test.... and test again...maybee he should consider to buy a 8x10 with an additional 4x5 reducing back for learning and testing
