I'm having troubles with uneven development when using the Jobo 2509n reels and a motorized base. What I am seeing is very uneven developing along the top and bottom edges of the negatives.
I've tried presoaking, using more developer, using less developer, etc... I've also used different developers, HC110 and Pyrocat MC. I haven't had any luck yet.
What I am resorting to is using 1400 ml of developer and doing inversion processing like a Patterson tank. I get good negatives this way, although sometimes I still get clear spots where the negative touches the triangle teeth at one end of the negative.
I'd like to work out a way to be able to use my motor base so I don't have to use so much developer and have a more automatic process.
Any help would be great!
EDIT: I am using a Bessler motor base that reverses rotation every 1 1/4 turn of the Jobo drum.
