    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.....

  2. Photographers Formulary is the name of a company who
    sells chemicals needed to mix your own processing solutions
    and also sells kits for popular formulas. 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 Knoppow/
    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.
