I finally broke down and bought a JOBO CPP-2 with expert drums for my 5x7 sheet film and am in the midst of doing new zone system tests. I have a few questions for experienced JOBO/sheetfilm users:(posted 9353 days ago)1. The manual says to use a rotary speed of 4 for the 3006 drum. Do I dare slow it down? 4 seems awfully fast and my times are running a little on the short side.
2. The manual says to use a 5-minute pre-soak. This seems like unecessary wet time to me, since I have always used a 1-minute pre-soak.
3. Any drum leveling tips? I find that when I level it, take it off the lift mechanism, then put it back on, the level has changed...
Any other tips from experienced users would be greatly appreciated.
