Second set of learning criteria was attempting to use Fidelity Medical Cassettes and S&S 11x14 holders and expect equal superior results. WRONG ASSUMPTION! After an experience with a soft moderate macro image (easy to do with ULF) that was correctly focused but turned out soft, I initiated a machinist review of film plane orientation. What I learned was that S&S holders and Fidelity Medical Cassette holders are nowhere near common. As a result I have two 11x14 film backs for my 11x14 DeardorffV11. One takes the S&S holders an the other is calibrated for S&S holders. With ULF the challenges with proper film / GG orientation is an absolute requirement. If you are truly serious about your tools, have this issue checked to ensure you are SPOT ON!
