Jaap, I notice you got a lot of info from a previous poster but I will
add a little specifically for Bronica.  The film width is 70mm and with
the Bronica 645 back you get an image which is 55mm wide by 42.5mm high.
You will either need to get a 70mm negative carrier or print in a glass
4x5 or something similar. I couldn't locate a 70mm carrier for my
Beseler 4x5 so I had a machinist friend convert a 120 carrier.  He just
had to move the pins out.
