A simple, classic solution for processing black and white negatives, Photographers' Formulary Film Developer 23 - 4Lfrom Photographers' Formulary Film Developer 23 - 4Lis similar to Kodak's D-23, and is a metol-based semi-compensating developer. This formula produces negatives with low to medium contrast, is ideal for zone system applications, and can also be used in divided or two-bath compensating development processes with sodium metaborate (Kodalk). When mixed, the working solution has an approximate shelf life of approximately six months, and one liter of solution is sufficient for processing about four rolls of 35mm film. The working solution efficiency can be extended to approximately 25 rolls if replenished with the optional DK-25 Replenisher. This kit contains enough metol and sodium sulfite to make 4 liters of working solution.

There are a variety of toning combinations that use this, and I recommend the Book of Alternative Processes by Christopher James if you're interesting in more.

[5.8 x 5 x 2.8"] Great developer, but I wish that PF would be less secretive about what's in the box exactly, how to mix it, how it works with some standard films, etc etc. I have to find all information from 3rd-party sources online. So I'm taking off one start for that. Otherwise, great developer. 5

[1.1 lb] Pyrocat hd is one the best Pryro formulas on the market, full film speed and great shadow details ! Easy to mix and use, if you process a lot of black and white negatives then this is a great buy for how much developer you get cost wise. 5

[Powder] I use it with Acros and 400TX/TMY 120 for amazingly sharp and gorgeous negatives. Lasts forever and easy to mix with distilled water. Use it at 3.5:3:500ml with extreme semi-stand (4 agitations). I have also used it as a two bath developer with equally great results. It is not fussy and when you expose properly, you will get a negative with beautiful gradation. 5

[5.8 x 5 x 2.8"] I am using this chemistry for black & white stand development. I am new to Pyrocat development and my initial rolls of 120 and 135 look good. I am noticing very sharp edges (acutance) that at first made me think the images had been extra sharpened by the scanner. The sharpening functions were not touched during the scanning process, so it is true, this developer does have high acutance. I like what this developer can do, but I did not like all the powdered chemistry that had to be mixed to make solution 'A'. There were four baggies of chemistry to mix for 'A' and some were very little amounts, but big chunks. I do not like powdered chemistry and will try and purchase liquid if it ever comes available. Because the films look good, I am giving this product review five stars, but I probably will not purchase it again in powdered form. 5

[Film Developer] I piled up a large stock of Ilford Galerie before it was discontinued. Weston Amidol and Galerie are possible one of the best natch I wnow. 5

[Powder] To bad bh stopped stocking this in store. I just discovered it as it’s much easier if you’re not printing a consistent high volume. With rc papers I love the tones and blacks as well as mid tones even on some very contrasty nyc midday shots. If stored unmixed even open in a dark metal vacuum corked bottle the concentrate has a great shelf life and mixing liquid is always much faster than powder dektol which I learned on and love still for 23 years. 5

[1.1 lb] I use it for Kodak T-Max 400 medium format films using the minimal agitation method. It does a beautiful job: fine grains and nice gradients. A bit sensitive for the way of agitation: too speedy rotation might result uneven development. I buy this dry version so I can be sure about the date from which the shelf life is counted. 5

[5.8 x 5 x 2.8"] We use the developer in our Optics and Holography class. No difference is apparent from the name brand item. It's a little more work to mix, but it's worth it to be able to continue with our experiments. 5

[5.8 x 5 x 2.8"] As a long time fan of Gordon Hutchings PMK but not of tray developing, I decided to try this formula which emphasizes ease of use and ability to use standard hangers (PMK creates developing marks when used with them). Although PMK is less expensive by volume, I can develop 4 8x10s at a time in one gallon (8 if I load back to back) with much less anxiety over scratch marks plus the ability to develop plus and minus in the same batch. 5
