I have been lurking on this forum for awhile, and it's time for me to ask a question. I'm coming back to film after a long hiatus. I've started shooting B and W again recently, and I have an interest in Pyro processing. After looking at a bunch of photos, I really like the look of Pyro. I thought I'd just jump in, but there are several formulations available. What would the best be for a beginner to pyro, but someone who has experience with standard developers, and has a background in chemistry? I've been leaning towards getting the PMK/Gordon Hutchings book combo from the Formulary, but I'd be interested in other folks experience in learning to work with it.
