    HC-110 Dilution H, 1+62 ?

    So being pretty new on this (started shooting analog and souping in March this year) I am now on my way to develop using HC-110 for the first time. I have two rolls (35mm) of Rollei Retro 80s, shot @160, following a recipe using HC-110 dilution H.

    Reading up on it I find that dilution H (as all of you most probably already know here) is double the water of dilution B. Looking at the HC-110 liter bottle it says dilution B is 1+31, which then means dilution H is 1+62 ..!!

    This is just fantastic, using my Paterson tank with 2 reels the total amount of fluid is 580 cc, 580/63 = 9,2 cc, meaning that my liter bottle of HC-110 will last for ages (108x2 rolls!!).


    I'm just amazed, is this really correct?


    Thanks!

    Not that it makes much difference but H is 1+63.

    Please note that you must always make sure that there is enough concentrate available to develop the rolls. Kodak recommends a minimum of 6 ml of the syrup per roll of 35mm or 120 film. Sometimes this means using more dilute developer than is needed to just cover the film. So using 9.2 ml for two rolls will not work.

    Read this www.covingtoninnovations.com/hc110 which has lots of information.

    Yes, I use it 1+60, for the simplicity of it. 10 ml of HC-110 syrup and 600ml of water to develop two 120 films. I use a syringe to extract only 10 ml from the bottle. This way you can develop 200 rolls of 120 on a liter bottle of HC-110!

    J.F.:

    You are correct. 9.2 ml of HC110 concentrate and water to make 580 ml. I have used HC110 (my dil. H is 1+60) with good results in 4x5. I am curious to see how this dilute a developer works for 35mm film. Yes HC110 is a very "fast working" developer, but is also exhausts quickly at high dilutions (added development time give very little added negative density). I would make sure you have enough developer in 580 ml (at 1+62) to properly develop two rolls of film.

    Best wished in your adventures with HC110.

    Lovely!

    And according to the bottle the syrup can be stored for 2 years!!!

    Thanks for the heads up guys!!

    Regarding "enough developer for two films", anyone who knows if the 9,2cc will be enough then?

    EDIT: Ok, I've read people using from 3-6 cc per roll, so I guess if I go with 10 cc for two rolls (simplifies the diluting), then I should probably do ok, right?

    Please read the Covington site mentioned thoroughly your questions will hopefully be answered.

    Thanks buddy, I've done that now, interesting reading indeed. I've also found a bunch of people using it 5cc per roll, and it seems to work just fine. I'll give it a shot tomorrow and we'll see how that turns out..

    I did read about the 6cc per roll, recommandation by Kodak, although I feel like Kodak plays it very safe. I am not surprised that 5cc does the work as well.

    Kodak wants people to succeed using their developer and may be a bit conservative. I use HC-110 1+49 with excellent results. That's 5 ml per roll. My only question was dropping down further to 9.2/2 per roll.
