I recently got an Omega D2V, and I am having a blast printing my 4x5 negatives! I have two questions: 1) Instead of cutting test strips from 11x14 and 16x20 paper, I was thinking that I'd just use 1/3 or 1/2 sheets of 8x10 and stick it in an area where I can assess exposure. I pretty much use Ilford MGIV RC. Is there any reason not to do this? I would be using the exact same paper (hopefully about the same age), just a different size. I understand there could be contrast differences if one of the papers was substantially older than the other. 2) I'm interested in trying some fiber paper also. Would exposure times be identical, or is some adjustment necessary? (I've never printed on fiber before) That is to say, if I am happy with a print I made on RC, can I use the same time and aperture settings for an identical sized fiber print? Thanks for helping a newb!
