After a number of years happily printing with my Omega D2V condenser head I decided to run some tests (a la Anchell) with a Stouffer Step Wedge (31 step) using a new set of 6" Ilford MG filters, MG IV RC Perle, and fresh Dektol with the following results: Filter #2 = grade 1 (iso range # 135) Filter #3 = grade 1 1/2 (iso range # 115) Filter #4 = grade 3 (iso range # 85) Filter #5 = grade 4 1/2 (iso range # 65) No Filter = grade 1 (iso range # 125) My condensers are clean, clean condition Nikkor 80mm f5.6 and my safe lights have pasted the Kodak test out to 7 minutes. After reading Anchell's results with a D5 I was expecting a solid grade 2 with no filtration as well as higher iso numbers from all my filters. Not that I can't work with these uneven steps in contrast, because I have been, but am curious if other using my setup have experienced similar lowered contrast results. Could it be my paper? Purchased 250 sheet box in October 2010. Would appreciate any thoughts as to why my results were so different from Anchell's.
