Pyrocat-HD in Glycol Film Developer is a high acutance developer formulated by Sandy King as an alternative to other pyrogallol based staining developers. Pyrocat-HD gives negatives of fine grain and full emulsion speed and is suitable for all types of development methods, including rotary, normal agitation, minimal agitation and stand development. Packaging in glycol stabilizes the formula to give a very long shelf life and long term consistency.

Not convinced that PyroCat HD - 1+1+100 - makes for higher acutance negatives than TFX-2 - 1+1+18 - with minimal agitation techniques, but perhaps the grain is just a bit finer.
Stand development is fickle 3.5 stars

I have wanted to try this for years but was " put-off" by tales of uneven development, streaking, etc. I really like the results (with TMY2) and have now embarked upon a testing regimen because the results are phenomenal. This may well be the best developer I have ever used.

Far better than mixing your own from dry chems. The glycol base helps with product life.
Cheers to PF for packaging this formula and putting it on the market
(and cheers to Sandy King for inventing it).

After reading a lot about Pyrocat HD, both positive and not so positive comments, I decided to give it a try.
I developed Ilford HP5+, Adox Silvermax and Agfa ADX 100 in the developer (actually together in the same tank)and found the results great. The tonality is beautiful and the films virtually grain-free at my type of enlargement.
It looks as I might make this my main film developer.

This formulation of a staining developer just seems to love continuous agitation without any extra base fog, very easy to work with in that regard.
The glycol version lasts a lot longer on the shelf.
Note: negatives may look thinner than you're used to, trust your final print!

After using most appropriate developers on the market (including my beloved PMK) I've found Pyrocat HD best for HP5+. Tremendous latitude in high contrast situations. In high desert New Mexico in November with harsh late afternoon light low angle light I held highlights and shadows well within good printable range.

Consistent results and great shelf life make Pyrocat HD my standard developer. It doesn't seem to stain HP5 and FP4 as much as I'd like (as with PMK) but it's also very good when doing stand and semi stand development. Great preservation especially of highlights for palladium printing.

What can I say? Pyro staining developers are an old, reliable class of darkroom chemicals. Much has been written about them & if you really want to learn the pros & cons, just Google "Sandy King pyro."
I don't have experience with any other Pyro formulas, let alone other developers aside from Rodinal. I have found Pyrocat-HD in glycol easy to mix and easy to use once I got my workflow ironed out. I used if for stand development of x-ray film, in trays or in tanks.
Except at the very beginning when I was still working things out, I've had no problems. Even development, good density, no bromide streaks, no oxidation. If you're willing to do a minimum of research so you can understand Pyro's strengths & weaknesses before you start using it, this stuff is for you.

using Xtol with good results but heard so much about Pyrocat that I wanted to try it. I tested, shot a few small runs of film and tested it. Quite a remarkable developer. The negatives look thinner but print well. By the time I got back from an Artist-in-Residence at Petrified Forest I was using it routinely. Ran my whole set of negatives in Pyrocat HD. It's a slightly different palette than anything I have used before. Too bad we can't upload examples. If you are on the fence, give it a try. Only downside was using gloves...I tray process by shuffling. No surges. I also had to get used to mixing using syringes for the 1:1:100.
Had Solution B precipitate fall out of solution. Sandy King said it was probably carbonate. I warmed the bottle in hot water and stirred it back in. No problems. I agitate it a little more often now. Examples on RobertLangham.blogspot

I have been using Pyrocat-HD for years and it's a great developer, with the ability to adjust dilution of the A, B and water to need. Also works great for stand and minimal agitation techniques for roll and sheet film. I use this developer for 35mm up to 8x20 sheet film, along with a 1:1:200 dilution for some X-Ray film I am experimenting with. In Glycol, it lasts a long time.
