ABC Plus Pyro -- Rollo Pyro -- is a formula developed by Harold Leban specifically for rotary processing in Jobo® equipment or BTZS® tubes. Thanks to Carl Weese for his painstaking testing and allowing us to use his information in our instruction sheets. The testing was done on several hundred negatives under a wide range of lighting conditions, being developed in Jobo® Expert drums. The results were clean negatives that can be processed in fairly short times at a relatively low (70°F) temperature in a single batch of chemistry. This formula however does not perform well in tray development because it produces a strong silver image with very little stain.

ABC Pyro is the oldest and best Pyrogallol formula. Yes, it's fickle and sometimes difficult to work with, but when it's on it yields superior results. I've tried other Pyro formulas, but will not leave this one ever again.
