    HC110 made simple.

    I thought I had posted this to the articles a long time ago, but I guess I didn't. So for the archives and the children, here it is.

    I like Hc110. Especially for roll film. I don't like the convoluted "working
    solution" dilutions and sub dilutions, or the short times some of the dilutions
    and sub dilutions create. It should be simple to use Hc110, like Rodinal.

    If you care to research, there was a method to Kodaks madness when they
    created the dilutions and routines for HC110, but they are of little
    convenience for the darkroom enthusiast. I get more questions about
    mixing and developing with HC110 than all other developers combined. It is
    a great developer that doesn't need to be complex in usage, so I concocted a
    metric dilution that goes by 50 (1+49) That means you use 1 ml of HC110 for
    every 49 ml of water in a direct from the concentrate dilution.

    Here is how to use it on roll film in an inversion tank, like Rodinal:

    First of all, forget about saving and replenishing it. Mix up what you need, use
    it, and dump it. It's so cheap under normal usage that saving it is fairly
    useless from a cost savings perspective, plus consistent performance is
    assured by using it one-shot.

    Next, forget about an intermediate working solution. Mix it directly from the
    concentrate. Use a small bottle and a baby syringe (available at any drug
    store) to mix directly from the concentrate. Simply mix it 1+49 . Use the times
    below as a starting guide (you may not expose the same as me, or may not
    have the same taste in negatives, so these are only suggestions that should
    get you in the ballpark to do your own tweeking)

    So without further ado,

    Hc110 direct from concentrate-1+49 , 68f 20c, agitate first 30s with 2
    inversions every 30s thereafter.

    ****Note to the civilized-Please keep in mind that this methodology is for the
    US version of the concentrate*****

    HC110 Notes

    JBRUNNER, thanks for this. Sorry if this has been asked before, but I noted that TMax 100 and TMax 400 have the same dev dilution but yet have the same dev time. How can this be? I would think there would be some difference??
    WYSIWYG - At least that's my goal.

    They are not the same emulsions.

    Jason, what minimum amount of developer per roll do you recommend? I found two recommendations one says 3ml another 6ml.

    As a recent convert from D76 (I finally used up what I had), this is most appreciated. I've been putting off developing anything hoping I could find some info like this. Thank you, thank you!

    Kodak dilution E 1+47 is close enought to 1+49 to provide lots of developing times.

    Since I switched to HC-110 I've been using Jason's information with great success for Tri-X, TMX 100, FP4+ and Pan F+ in sheets and rolls.

    JBrunner,
    What do you like about HC110? I used to use it and found it nice as super diluted compensating developer and use to have a great method for pushing HP5 with semistand. I've since switched to X-Tol and pyrocat hd. I'm just curious to why you like it for roll film. I do really love working with concentrated developers.
