Pyro - Processing Fexibility

greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread

With all the positive talk on PMK Pyro, I had to see what all the hub-bub was about. I ordered the PMK liquid and recommended fixer from the Photographers Formulary. It arrived last evening.

The instruction booklet states that PMK cam be used over a temperature range. They say that no degredation of the negative or image will occur using higher temperatures. Here in south Florida the tap water runs between 78F and 80F. They say to decrease the development time by 4% or each degree of temperature rise over 70F.

That means that I could process film at 78F - 80F and decrease the suggested development time by 32% - 40% as a starting point. And wonders of wonders I will have no degredation of the image or negative.

Is this possible? Could someone tell me if I finally can process film without ice or a chiller? This sounds too good to be true. Sorry for being long winded but I am still cautiously optomistic.

HI Mike

Just a word to warnyou that you must use a fixer with a hardner at that temp. range. Run some tests I think yoou will be suprised. If you realy get into it get the Book of Pyro from the formulary.

I offer a chart of my developing times at http://www.unblinkingeye.com/Articles/Developers/Times_PMK/times_pmk.h tm. I do occasionally use 80 degrees, without hardener, but never hotter than that. If my tap water is hotter than 80 degrees I add a little refrigerated water to get the temp down.

Thanks for the answers.

I ordered The book of Pyro today and took a look at Ed's development times on his web page. I wil begin testing this weekend. Thanks again
