The Jobo 4X5 sheet film spiral and tank handle pyro very well, as the
sheets are kept separated so the back can be stained evenly. The 11X14
and 16X20 sheet film drums also work. Too bad they don't make the same
thing for 8X10, that tank doesn't allow the solution to flow over the
back.
I have noticed a 100% increase in time for Pt/Pd printing comparing pyro
negs to unstained ones.
