    Lee;

    Every single source agrees that 30 minutes for film, and maybe less for RC in that device will give archival washing. The RC papers have thinner emulsions. Also, the fixer is important, the use of hypo eliminator, toning.... All of this is crucial in making high quality prints.

    The articles allude to 1 hour for FB.

    That's also Steve Peterson's recommendation for FB. (The other times you mention also match his. For other readers, Steve is the owner of Summitek.)

    He quit manufacturing for reasons of low volume, but his web page says that his fabricator may take direct orders on some items.

    film, but it can't hurt. Then I do agitation cycle, except
    I usually agitate more (20, 25, 30 instead of 5, 10, 15),
    and I let it sit for a 30 seconds or a minute after each
    agitation cycle. During this period I start cleaning up
    the bathroom a bit (wash funnels, etc.) Seems to
    work so far (knock on wood).
    At least you do not run the water for 5, 10, or more
    minutes. A running water wash, film, RC, or FB, is a
    Most Inefficient use of water.

    The Ilford method, fill & dump, is very efficient and
    comes with a considerable amount of agitation; 5, 10,
    and 20 inversions. In effect the time of each soak/wash
    is increased with each change of water.

    The first wash is short, removing primarily surface
    fixer. Five spaced inversions should be plenty. The
    second and third washes, IMO, should be more soak
    and certainly no more in agitations; the 10 and 20.
    Spacing those 10 and 20 I believe to be a good
    idea. Since the method uses so little water
    there is no reason to use it other than
    at Room temperature. Dan

    Dan;

    The wash you suggest may or may not be good depending on operator technique and water supply. That is why I have given the original suggestion by Kodak and others here of a use of continuous water washing. If you use your method, it is virtually mandatory that the person test for residual silver salts and hypo if they wish to get maximum permanence.

    I have given the data from Mason earlier in this thread. I also suggest that you consider that most people refer to two levels of wash, normal and archival. You should give some information on the differences if you are to "approve" a given method.

    I have found, over the years, that the so called Ilford method is much more intolerant of error. Sorry. I still have to disagree with you.

    You didn't read the entire thread? Post 41 summarizes part of it.

    OMG, then why did we have 5 pages?

    What is it that we're washing out of film anyways?

    What's it more soluble in? Water or gelatin?

    Dry does not go with analog photography! (well, except for Polaroid)
