    Craig, my only published fixer was posted here by Jdef (IIRC). For the time being, that will have to be the only one.

    My plans are to develop a universal B&W fixer that will also serve to work with other ingredients as an economical, fairly stable film blix for E6 and C41. It will then be basically a very rapid B&W fix, part of a blix (with an add on part), a color fix and it will allow for very very rapid wash with good image stability. It will work with both film and paper and with B&W and color.

    Since it is still under development, I don't care to comment further on it. My ultimate plans for it are open ended at the present time.

    I use it myself in my own darkroom. I am currently on version 7, and am running wash and keeping tests.

    Thanks for your interest.

    PE, that sounds very, very interesting. As a person who does C41, E6 and B&W, it may make life quite different in the dark room.

    I await, with bated breath.

    Mick.

    I think it's a fetish. Years ago the term "speed freaks"
    was used. I not going to use that term because I
    don't travel in those circles which use such
    terminology.

    Last night I used 1/2 ounce of unadulterated A. Thio.
    in a solution volume of 16 ounces to clear, and some, a
    120 roll of Delta 3200. I checked at 6 minutes and it was
    clear. I gave it another 2 minutes. A following iodide test
    did show some margin.

    One of these days I'll get around to testing wash
    times associated with highly dilute one-shot-and
    -done-with-fixers. First though I've got to find
    out how to prepare a permanganate solution
    which does not produce a precipitate. Dan

    Dan, I'm not a speed freak. I want to use less fresh water for washing.

    I want to save time in the darkroom. I want to save time keeping temperatures at 100 deg F (38 deg C).

    All hit you in the pocketbook or affect the environment.

    Those are my targets.

    Don't pay any attention to me. My minimalist
    regime dictates S. or A. Thiosulfate unadulterated.

    BTW, that Delta 3200 I wrote of has the very slightest
    pink hue. I'd average the exposure of the roll at close to
    zone 5. For that film I think 2/3 ounce, 20ml of 60%, a more
    correct amount. Clear and then some time will likely run about
    6 minutes. I've not made exact time tests. I only mention
    this so as to head off any misgivings on the part
    of any interested. Dan

    That is interesting. I'm using TF4, as I stated earlier, cause I use a lot of PMK. But lately, I ran out and started using Clayton for film. It still stains. I don't know any better.
    Will the fixer you will be formulating be suitable for staining developers?

    Eric, IDK yet. I have some of those developers to test with the fixer, but have not gotten around to it.

    It may or may not work. I'm hoping it will, as there is no reason it should not.
