In fact, the Arista APH and APHS films stain very well, almost as much as
TRI-X and FP4+.

Rollo Pyro is a modified Pyro developer, very similar to PMK but with the
addition of ascorbic acid and EDTA. It is used by many photographers

the formula in the archives (or one very similar), posted over a year ago
by Harald Leban of Austria.
