I posted this on the 26th in another thread but a separate posting is more appropriate:
On Wednesday I made eight Ilfochrome prints, 4 through a fresh batch of 600ml solution volume, and then 4 through the same 600ml a second time around. 140ml being pumped into the Jobo 2830 tank.
Solution use and black level:
1. Fresh solution, blacks "very black".
2. Reused solution print '2B', slightly less black.
3. '3B' less black again.
4. '4B' - not black.
I can understand why the reused chemistry might give differing results to the first batch, but why the varying black level as prints progress through the second batch?
