I have been fiddling with the idea of using a dilute Pyrocat-HD "A" solution as the first bath, followed by a dunk in a "B" bath with either: (1) Carbonate. (2) Metaborate (3) Borax.

This would be a split one-shot. I am testing it with Special purpose high contrast films like Kodak Tech Pan and Efke 25.

However, for high acutance compensating development in normal pictorial photography; I will stick with Pyrocat-HD and either minimum agitation or stand development. I use both methods, depending on the film and the SBR.
