I just recently started to scan my 8x20 negatives I developed a year ago or so and I discovered that I have a serious issue in my development.
In my third negative I see same uneven development, it clearly shows in highlites. The unevenness is always the same, in direction of JOBO rotation, on same places. It looks like different amounts of developer are running over the negative, making it uneven?
My development is as follows: I use JOBO levelled perfectly with 16x20 inch print drums, it's a print drum with the extension, running slightly higher than F speed, using revesal-rotation mode, developer is X-tol 1:1, I use 1 liter of developer just to be on a safe side.
I use same technique with 4x5, everything is just fine and even.
Unfortunately, this development technique make development problems on 8x20. I also have 6063 drum but I think that one would be just too big.
What should I change? Running on higher speed? More developer? Lift the negative in a prin drum?
Thanks.
