From: Larry on 21 Jun 2008 19:46 Hello, sorry, it's been a long time since I read this group. I need a book of film and paper chemistry recipes. I believe there was a book (out of print) called "the Photographer's formulary". does anyone know of this book or a similar book??? Please email me with a reply as I don't check these posting regularly. Thanks in advance.... BTW if anyone wishes to sell their copy..... Larry Kriese

They are on the web and are a very good source if you intend to mix your own. See their site for more. What you are thinking about is the _Darkroom Cookbook_ by Steve Anchell. I believe the second edition of this is still in print. It has a good collection of formulas but I warn you that it has the same problem as other collections: the authors probably never tested very many of them. The book is available from many sources (the Formulary may even have them) do a Google search for it. The Digital Truth site at: http://www.digitaltruth.com/ Has a large section of on-line formulas for developers and other processing solutions. Also see Ed Buffaloe's site at: http://unblinkingeye.com/Articles/Developers/developers.html Which has a pretty good explanation of the functions of the various components of developers. Also see Ryuji Suzuki's site at: http://www.silvergrain.org for some very reliable discussion of developers, fixers, etc., by someone with an excellent knowledge of modern chemistry. Also see a small collection of stuff incuding a bunch of conventional Pyro formulae at: http://www.nonmonotonic.net/Photochemistry/Richard%20Knoppow/ Also, I've posted a lot of formulae to rec.photo.darkroom over the years as well as the Pure-Silver mailing list. Check Google for these posts. This is not at all an exhuastive list of stuff available on the web. A Google search will find more. Note that not all published formulas are practical. Many are very old and never worked well but have been carried over for many decades because it was simple to "cut and paste" into later books. Some were more alchemy than chemistry. Some are based on serious misunderstandings of the the functions of chemicals in developers. A great many are simply small variations of the same thing by different manufacturers and are essentially identical as far as practical performance. For example every paper manufacturer has a developer similar to Kodak D-72 (essentially identical to Dektol). AGFA and Ansco, which they owned for some time, specified potassium salts for some developers. While potassium may have slightly different photographic activity than the sodium equivalents the main reason AGFA used them is that they had a very cheap source as by-products of their chemical manufacturing business. The same for exotic developing agents, mostly they have no advantage over conventional ones and that's why they fell into obscurity. So, experiment but don't go broke or go through a lot of trouble over stuff that is expansive and hard to find, most of its isn't worth the bother. -- --- Richard Knoppow Los Angeles, CA, USA dickburk(a)ix.netcom.com -- --- Richard Knoppow Los Angeles, CA, USA dickburk(a)ix.netcom.com
