My rollo Pyro kit got in tonight! I'll be reading Gordon's book along with repairing my leaky unicolor drums tonight. If Mother nature cooperates with me, I'll be out shooting 4x5 and 8x10 test shots tomorrow. 4 sheets per scene. 1) Rollo Pyro, 1) D76 1:1, 1) D76 1:0, and one safety in case something goes wrong. I'll post my results.
