I've heard about this pealing of the paper and also waxing and other
methods; always seemed like a fudge to me. I'll have to have a look
around and see if I can get hold of this ortho film stuff, although
I would be a bit worried about processing it and I've never processed
sheet film before.

So that would be a short contrast range rather than a high range...? Is
there anything you did to achieve that...? I'm not that up on shooting
for a particular density, I just point, shoot and hope for the best
normally.
