I would try to find a 4x5 contact frame for contact printing. I have an old 4x5 frame and an 8x10 one. The 4x5 is much easier to use. There is not so much worry of your negative being printed a little sideways with a 4x5 frame. It's hard to get the alignment right with so much play. Does anyone make new 4x5 contact frames anymore, or am I stuck using my grandmothers from the 1930s (which is fine but it has a broken spring)?
