    Going to order some Photographers Forumlary Amidol for my newly bought AZO. This will be my first attempt at contact printing large format negs. Should I get the regular amidol or Westons? What is the difference? (besides $2)

    Here's a recent related question:

    http://www.michaelandpaula.com/mp/AzoForum...&GID=1908&CID=1

    I've only tried Michael A. Smith's formula, so I can't comment on the others, but I've heard they don't last nearly as long and don't work as well. Check out his site for the formula, developing times, technique, etc.

    My $0.02.

    You should get your amidol from Mike Jacobson at:

    http://www.artcraftchemicals.com

    Mike is quite familiar with all of Michael Smith&#39;s formulae.

    You will also need sodium thiosulfate pentahydrate (plain fixer), citric acid, sodium sulfite and sodium (meta)bisulfite. Also, I put benzotriazole in my amidol but I seem to be in the minority.

    Figure about 5 lbs. of fixer crystals for each gallon of working solution. I have gotten pink stain on my prints when using ammonium thiosulfate based (rapid) fixers with amidol. I didn&#39;t always get it, but it absolutely ruins your prints when you do. Better to be safe than sorry when working with precious amidol and Azo.

    Yes, I second the comments on Michael Smith&#39;s formula. It can be found on their site michaelandpaula.com. The reason that Amidol gets the "bad rap" about rapid exhaustion is that the other formulas do not use citric acid. The citric acid stabilizes the formulation and hinders rapid depletion through oxidation. Artcraft Chemicals is less expensive and very accomodating on their chemistry. I have bought from both Formulary and Artcraft and so I have a valid point of comparison. Not that Formulary is "bad", please understand, but that I have found Artcraft to be more favorable.

    If you plan on buying bulk chemicals (highly recommended) you will need something that will allow you to weigh in grams. There are ways around this but I have not used them so I can not comment on their accuracy.

    As an aside, I learned yesterday that both Formulary and Artcraft were reportedly temporarily out of stock on Amidol...It appears that the secret is getting out. Good luck to you.

    Wow, 5 lbs of thiosulfate per gallon of fixer...I use 2 lbs and 4 ounces of sodium sulfite. I don&#39;t know how a person could get 5 lbs into solution. Even the Kodak F6 and F24 formulas call out 32 oz of Sodium Thiosulfate per gallon... the Kodak formulations do have additional ingredients apart from the plain hypo formula that I alluded to at the outset.

    Agreed. Just tell him you want a one-liter Michael A. Smith amidol formula (or whatever size and quantity you want), and you can get everything pre-measured in zip-lock bags. (I actually got a little more KBr last time). A 1 L kit will develop more paper than I can do in a printing session.

    When I don&#39;t have amidol, I use Agfa Neutol WA, and failing that, Dektol.

    Brian,
    repeat after me, "DON&#39;T buy the formularly amidol package". The results don&#39;t look nearly as good as Michael A. Smith&#39;s formula. I almost gave up on azo before using the Smith formula. there is no comparison&#33;

    as pointed out Mike Jacobson at artcraft is the place to get it. I didn&#39;t have a scale so he even mixed the formula for in packets for me, at a very reasonable price.

    Aggie, are they into mixing kits like Artcraft? I&#39;m not interested in doing it on my own, that is why the PF kit was interesting to me. I emailed artcraft to check prices and availability for their amidol kit and hypo.
