    kodak Tmax RS developer formula

    Where can I find out Kodak tmax rs developer formula so I can make it by myself? It looks like kodak tmax rs developer was DISCONTINUED by Kodak. BH is no longer ship them to buyers, store pick up only.

    I don't think you can. It's a proprietary product. The MSDS probably will give some general clues.

    It looks that the 50L version can be shiped: https://www.bhphotovideo.com/c/produ...plenisher.html


    With sheets you may try regular "non RS" TMAx deveveloper. It is not recommended in the datasheet for sheets because it may provocate dichroic fog in the sheets. It looks that this only happens with some kinds of tap water, so if you get dichroic fog with in sheets with (non RS) TMax then you may use some mineral water or distilled water to make the working solution.

    I emailed Unique Photo Superstore to see if they would be restocking the Kodak Tmax RS developer to make the 1 gallon size and was told that it had been discontinued. Freestyle states it has been discontinued on their website. I've used Tmax RS for all the developing for my Tmax sheet film and that smaller bottle that makes the 1 gallon sure was convenient. The larger size bottles would probably expire before I could use it all.

    TMax RS keeps a long time in my experience if it is kept in full bottles. I had the big double bottle version some years ago when I could get a really good deal on it. I refilled it into smaller glass bottles filled to the brim, and used it over three years. Never had a problem even after the three years. And I just ordered another set of the large bottles to do the same again.

    Adding to what Arne pointed.

    Even in the case you cannot use it all, still the large ammount has a 25% discount, compared, so even in the case you can spend only the half you would have a not that large cost increase.

    If you plan a long shelf storage then you should perform a "drop test" on film ends, by (lights open) allowing to fall a drop every minute on a film end and later fixing you have an strength reference. Then you repeat that test over time to see if strength changed, you may correct development time or chem concentration to keep consistence, and you won't ruin sheets.

    By placing the compared strips with the drop test on a light table you will see what you have to do, but also you may scan the strips alongside (reference and last) to see the gray levels in the different "drops", to compare numerically if you want.

    I once switched to non-RS TMax developer for sheet film due to difficulties getting RS. Even with distilled water I somehow managed to get dichroic fogging.....YMMV

    Hi Phil
    That's because the non rs formula is not made for sheet film. Back when tmax developer came out I was directed by someone at the Kodak pro help line to use the non rs developer by mistake
    and it didn't give me dichroic fogging right away but only after about a box of film, and sadly when I was using it for a job. The good folks at Kodak told me to toss the film and denied ever telling me to use the developer
    it was a real lovely situation... I'm local so I called Paul Krot at Sprint Systems and he me mix farmer's reducer using his fixer and putting the film back in my hangers and soaking the sheets 1 at a time until the fog was eaten away.
    if you still have fog on your sheets ( and didn't toss them as I was directed to do ) its worked OK. I think the formula I was told was 1 plastic 35mm can of ferri +1Lof water, and 2+8 of Sprint Speed Fix..
    The funny thing is, it was kodak's own farmer's reducer packets I was told to buy, and kodak's finest didn't even know to use it. In the end i have never used their tmax or rs developer ever again, and I never missed it.
    I still use Sprint Chemistry when I don't use Coffee Based stuff and Ansco 130. Their developer is formulated in a way that when you develop for extended amounts of time
    it doesn't block up your highlights, and their fixer is fantastic. Paul and Marlaine at Sprint are the nicest people I have ever met.
    enjoy your coffee

    I’m going to wait and see if it comes back from the new supplier like Xtol and HC110.
