  1. Perfect Replacement 5 Star Review

    Posted by on 30th Nov 2021

    I'm an "old school" Cibachrome printer. We're a rare breed, maybe 3-4 left actively printing in North America. The paper can be frozen but the originally packaged chemistry must now be made from scratch. The chemistry's raw components were delivered from Sweden and cool stored in my basement. Alas, I went to make my first batch and discovered two components had been contaminated. The Potassium Bromide from Photographer's Formulary was used as a replacement and performed exactly as needed for making the Developer component. Thanks much!


  2. Bulk Chemistry The Way To Go! 5 Star Review

    Posted by on 16th May 2021

    Recently, I bought a new package of Dektol, and I noticed Kodak changed the packaging, only to find out that they are outsourcing their chemicals to third party manufacturers. The new packaging is also not light tight, so I am convinced the chemical is gravely compromised. The chemical itself was murky brown, similar to stagnate, muddy water, which left my prints flat, and the rest of the paper a sepia tone, I don’t want.

    After researching on the internet and Steve Anchell’s book, “The Darkroom Cookbook,” I bought several chemicals from Photographer’s Formulary: Glycin, Hydroquinone, Metol, Sodium Carbonate, Sodium Sulfite, Potassium Bormide, Potassium Carbonate to make Ansco 120, Ansco 130, Angel Adams Ansco 130, Der Beers VC developer, and to experiment with some warm tone developers too.

    The results were WOW WOW WOW! Simply fantastic. All the chemistry is fresh, easy to mix, and the results were amazing. I have never seen such tonalities in my prints before. Now, I want to go back reprint 30+ years of work. I will never go back to the inferior store bought Kodak products, which have degraded overtime.

    Mixing your chemistry is easy, fun, and the results are amazing. Ordering the chemicals were quite easy from Photographer’s Formulary, the items were well packed, and arrived a day earlier than expected. If you love being in the darkroom, I would highly recommend to start making your film and printing developers.

    Excellent product, works like a champ. No issues in weighing, mixing or using. Prevented film fog perfectly.


  4. Potassium Bromide was mostly chunks 4 Star Review

    Posted by on 29th Apr 2016

    Potassium bromide is used in grams or fractions of grams. I didn't find crushing the chunks into useful sizes easy and was difficult to portion.


  5. Potassium Bromide 5 Star Review

    Posted by on 31st Dec 2014

    This was exactly what I needed. This is the most pure potassium bromide I have dealt with for photography. As another review said, there are some big chunks due to crystallization so you might need to crush them to make them easily soluble.


  6. Great for Caffenol C recipes 5 Star Review

    Posted by on 28th Oct 2014

    This stuff is perfect for use as a restraining agent in Caffenol C developers. There are some big chunks in the jar, but seem as though they would be easy to crush up.


  7. Potassium Bromide 100g 5 Star Review

    Posted by on 25th Sep 2014

    Ordering was easy, with a good selection of sizes.

    Shipment was done incredibly quickly, and it arrived sooner than I expected.

    This KBr was used for Black and White film development, measured on a 0.01g digital scale, and performed as expected at the recommended weight of KBr.

    In the bottle, there was some powder and some lumps. The lumps come apart fairly easily with some pressure applied to them, and obtaining the correct weight is easy.
