    HP5+, Pyrocat, Extreme Minimal Agitation

    Curious if any one is doing this with HP5+ (Pyrocat [MC or HD], Extreme Minimal Agitation) and if so, what dilutions as times are you using.

    Thanks.

    Why would someone want to use what I see as a semi-stand development with rapid exhaustion developer?

    What is the goal?

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    Well, the reason I want to do that with HP5+ is to make negatives as good with a faster film, as the ones I'm making that way with FP4+ already.

    Initially, the goal was to get the edge effects and accutance of a staining developer in EMA with a product with a long shelf life that I could buy in liquid form and measure out in small quantities, on a per-use basis. I tried Pyrocat MC in glycol with FP4+ and I like the results.

    I would use the same dilution as with FP4+, 1:1:200. Start with 45 minutes as a developing time and see if you like your results. If your negs are too dense, drop back to 30 minutes and test from there.

    Are the results with such a developer that much different than simply using the standard agitation? If I understand correctly, the developer already is the type to enhance edge effects.

    TFC, I'm using 1.5:1:200 at 60min for TF4+ with an SBR of 6, per Sandy King's input. I'm thinking of trying that. with a upward time adjustment of 1.125:1, since I'm seeing that with most developers, that's about what HP5+ requires compared to FP4+.

    I was hoping to get some input from others using that film, developer and agitation method.

    Robert, I'm after the micro-contrast that occurs with the localized exhaustion of the developer in contact with the high-density areas of exposure. It's a feature, not a bug.

    Good luck with your project. I used Pyrocat-MC for a couple of years, at the same time as a friend of mine was doing Pyrocat-HD. Different films, Tri-X, FP4+, TMY-2, Neopan 400. We were both very happy with it, and both arrived at agitation every three minutes.
    Then, at almost the same time, we both encountered problems with uneven development. He ended up with TMax and I went with Xtol and Edwal 12. He has recently revisited Pyrocat, but with rotary development. A little bit less acutance, but nice negatives that seem to print very well.

    For me, I never went back, because I didn't find that much of an improvement in acutance or sharpness, not enough to matter. The replenished Xtol is mighty sharp, and doesn't suffer from the weird highlight tonality that I get from extreme minimal agitation. But you may shoot subject matter that's a little different and it is more noticeable.

    I think you can probably have some good luck with it. All I'm saying is that if you get unevenly developed negatives, don't be surprised. It may never happen to you, but I think it's fair to let you know there is a distinct possibility of it.

    That seems like an awfully long time. How do the negatives print? Minimal agitation doesn't like overdevelopment. I use 1.5:1:175 for around 40 minutes at 70°F with a normal negative. I agitate vigorously and continuously for the 1st minute and then for 10 seconds halfway through development. They can look pretty thin and still print beautifully because there's so much stain.
