Pyrocat-HD Film Developer is a semi-compensating, high-definition developer, formulated by Sandy King as an alternative to PMK. The advantages over PMK that Mr. King cites for his formula include an approximately 1/3-stop greater effective film speed, 10-15% shorter development times, more consistent staining action, lower toxicity, and no streaking or mottling with reduced agitation.

If you know what Pyro developer is than you also probably know how to use it and why. This formula works well and is the result of interesting extensive experimentation you can easily read about on the web. One added advantage is its lower toxicity and variables (different dilutions at different temperature) that you can use to fulfill your needs and the needs of your negative. Will buy it again.Kudos to Photographer's Formulary for carrying this product.

I did a test with Pyrocat HD diluted 2:2:100 developing Ekatascan X-Ray film @74 degrees from 7 min 30 sec. This developer is really amazing. It brought out a tonal range that I had never seen or thought possible by this type of film. I will be using it exclusively for Portraits from now on. I do not suggest using 2:2:100 at 74 degrees. It was just a starting point for me and I still think that I need to refine the process...perhaps 1:1:100 at 74 for 12 min on the next attempt. However you use it, the results will be amazing. Great product. I will be buying more in the future.

Thanks to photo-formulary for making this developer available in liquid concentrate. Easy to mix, long lasting, very economical and most importantly a superb film developer. You know how good this is, I don't need to tell you... I have been using ID11 for 20 years and it was consistent and reliable but Pyrocat-HD is next level. Shipping to Australia is not inexpensive but it is worth it as this developer is not available here. It only took about 7-10 days to arrive which I think is excellent.
