    You know, I might just start using Pyrocat-(HD|MC) now...

    It's most heartening to behold this collaboration, instead of seeing snake oils peddlers trashing each other's products.
    Using film since before it was hip.

    I've learnt so much from both of you over the years. From Sandy's pyrocat-HD, and Kallitype printing (yes, Sodium Citrate developer rules!), to Mr. Gainer's great reads in PT magazine, and Vitamin C developers...
    Thank you, gentlemen!

    If you find the need you could also mix the Pyrocat-P formula with glycol, substituting ascorbic acid for metabisulfite and eliminating bromide.

    And it is really easy to do since all of the chemicals go into solution easily in warm glycol.

    Pyrocat-P has a very interesting edge effect that is quite different from both -HD and -MC.

    I was about to suggest that. While you are getting the p-aminophenol be sure to get the base, not the hydrochloride, if you plan to dissolve it in glycol. You can also make 500 ml of Rodinal clone with 40 grams of the p-aminophenol, 85 grams of sodium sulfite and 13.8 grams of sodium hydroxide or 19.3 grams of potassium hydroxide and enough water. Now for a few turns around the mixer you can have two of the best developers, one staining and the other not. Each has its character.
