PMK Pyro-Metol Kodalk Developer for Black & White Film (Liquid) is rated 5.0 out of 5 by 13.
Rated 5 out of 5 by from Fantastic! I have used D-76, HC-110 Dil H, T-Max and this developer has replace all of them for my medium format work. I normally shoot HP5+ and Delta 100 and both come out beautifully in this dev, I soup the HP5+ for 12 minutes at 68F. My most stunning results come from Delta 100 in PMK for 14 minutes at 70F. I can't think of one problem with this dev although it is a good idea to either have a graduate that can measure down to 5ml or use a syringe graduate because of the small amounts of part A (10ml) and B (20ml) required for mixing 1 liter of dev.

Rated 5 out of 5 by from Excellent developer I've been using PMK Pyro for about 10 months now and would recommend it to anyone who is serious about traditional black-and-white photography. It is very cost-effective, as I have had the same bottles of solution since January, even as I shoot around 60-80 sheets of 4x5 film every month. The staining action helps to give a smooth tonal separation in the highlight details and reduces headaches from tough exposures that blow-out skies or bright lights. When matched with a warm-tone paper and Selenium toner, making rich prints is rather simple. I recommend reading Gordon Hutchings's Book of Pyro as a guide, as this is his formulation of the classic film developer and it has some peculiarities to keep in mind while processing.

Rated 5 out of 5 by from The best developer for black and white I have use D-76, Tmax, and HC-110 dilution B developer. All these developer have a problem when it comes toward mid-tones. Of course you can pull your film to stretch your mid-tones, but even that when can we have developer that can extend and gives full details of images that is almost impossible to retain with these other developers. Pyro PMK is the answer to that. I normally develop my TMAX 100 at 13 mins and the result is astonishing. No word can describe the details the negative brings out. It was at night and the shadow that is almost impossible to make out in the background is fully expose and even the stuff that is inside the window of the background is fully expose. I am amazed.... I recommended to anyone who wants the best negative that is. Just be aware, you must air-dry it, not air-heat dry. No perma wash or photo flow cause you will erase its stain. Wash with water for 30 mins.

Rated 5 out of 5 by from PMK developer results I usually am developing Ilford Delta 100 or 400 and this system works very well. Negatives are easy to print and beautiful. The long life of the concentrates is a benefit to me because I sometimes have long gaps between darkroom sessions. One time I let the B solution get cold and crystals formed in the bottle which I was not able to get to re-dissolve. The only minor inconvenience is that the developing process requires constant attention (agitation every 15 seconds).

Rated 5 out of 5 by from PMK Pyro Developer I have been developing my own film for over 35 years. This developer has been my standard for the past ten years and is all that I use now. It produces incredibly sharp negatives, with exceptional consistency, such that you are assured of the same results over and over. Works particularly well with Ilford films, such as Pan F, FP4 and HP5.

Rated 5 out of 5 by from Outstanding Product I've used PMK for over 25 years. This developer gives me consistent, repeatable, reliable results. A very long tonal scale. Great shelf life. Caution must be taken in use i.e. keep away from skin. Can stain almost anything including clothes, counters etc. Toxic. With precautions safe to use. Read label carefully.

Rated 5 out of 5 by from Sharp, Staining, and Fine Grain Great film developer for those seeking sharp negatives and fine grain. Also the rendering of details in shadows and highlights are amazing. Don't let the stain on the negative worry you, or really dark scans. Also best to wear gloves when working with this product.

Rated 5 out of 5 by from Excellent Developer Best for large format sheet films. This developer yields an excellent Pyro stain that holds highlight detail. I particularly like it with Tri-X, Delta and TMax400.
