I ended up shooting with my 4x5 monorail and my Rodenstock 135mm enlarging lens, turned around backward, at f/32, 1:2 magnification onto film (f/90 effective). The contact prints look pretty nice so far but I haven't enlarged them yet. I don't have a fancy bellows setup for 35mm and I needed significant geometric distortion correction. My bellows is just barely enough, after I cut a custom lens board out of cardboard with 2 inches of down shift built in.
I still don't fully understand the fundamental differences between shooting to a smaller magnification on the negative and enlarging more, versus shooting to a larger magnification on the negative and enlarging less. Is it better to shoot 1:1 on 4x5 and enlarge to 8x10 or is it better to shoot 1:4 on 8x10? I'm still not sure.
