Back for more help! I have a crown graphic with a non rotating back but I shoot mainly uprights as it were, I have asked a related question before but the advice I got(file some slots) is more than I would like to do to the camera and I am not confident enough to do so. I am thinking about putting a rollfilm holder on it, the RB 67 back is a fit I believe, does this include the rotating part? if not can I fit a 6x6 back? I am trying to mitigate the fact it has tilt on one axis only before having to move it on, which I don't really want to do if I can help it cos it is nice.
