The following is a list of resources for finding supplies to various alternative photographic processes. They are all located in North America. Bostick & Sullivan. www.bostick-sullivan.com 505-474-0890 This is a family operated business located in Santa Fe, NM. Along with promoting alternative artists and hosting events, like the Alternative Photography International Symposium, they have a great variety of darkroom chemicals, mostly featuring those highly specialized for alternative processes. Graphic Chemical & Ink Co. www.graphicchemical.com 800-465-7382 Located in Villa Park, IL. This is an excellent source of lithographic and graphic inks – all colors in a variety of sizes. Their products generally seem reasonably priced. They are extremely helpful, though this is a site more geared towards lithographic printmaking than photographic processes. Photographer’s Formulary, Inc. www.photoformulary.com 800-922-5255 This is "the" place for all alt-processes geeks who might just be in the market for liquid gum arabic or amidol. They sponsor heavy-hitters in the darkroom and alternative processes arena, such as Tim Rudman, Dan Burkholder and Theresa Airey, offering workshops in various places around the U.S. as well as on location in Montana. This is a fun and informative website to peruse, being also a great resource for more basic darkroom supplies and chemicals. Indigo Instruments. www.indigoinstruments.com 519-746-4761 Located in Ontario, they ship from a New York distribution center. They are suppliers of all types and sizes of measuring units and tools, including graduated cylinders, beakers and flasks. These items are of great use when mixing and measuring your own chemicals in the darkroom. There is no printed catalog, but the site is nimble and user-friendly. Feel free to add any companies you know of.
