While this question deals with darkroom procedures, it is unique to large format , hence my posting here. While the archives have many helpful posts and answers on Tech Pan development i n roll form, I'm looking for anyone who may have experience developing Tech Pan sheet film (4X5 in a Jobo CPE2/with lift.) in technidol. Kodak does not specific ally discourage this, but provides no information regarding development times or techniques for this dev/film combo other than 8 min in a tray.
Using Kodak's standard Technidol dilution for 4X5 (which is 1/2 of the dilution for roll film), I tested six sheets--two at 8 min, two at 7 min, and two at 6 mi n--and at the tray development time, contrast was markedly higher at 8 min. At s ix minutes, contrast was a fairly low, and at seven, looks to be spot on.
While you may be thinking "he's answered his own question" I am wondering if any one else out there is using a Jobo to process Teh Pan in technidol and if their results approach mine. I don't have a densitometer, but just from eyeballing con tact sheets made on grade two paper, I think I may have nailed down about the ri ght time. I'm hesitant to test much further because of cost reasons, hence my qu ery.
Thanks,
Doug
