TMax RS developer as "one-shot"
I've looked around quite a bit both on this site and on others through Google but nothing I can find is really clear.
I've been finding my development times on the massive dev chart and my question is based on the stock solution idea that's on there.
As I mentioned in the title, I don't want to use this developer as a replenishment system, I simply want to use it to avoid this dichroic fog that apparently can accompany normal tmax developer used with sheet film. I bought the smaller size at the local photo store, I believe it says it makes a gallon of stock solution. It comes with Part A in a plastic bottle, and Part B in a very small pouch. I believe my first move is to mix B into A, but what about when I want to use the developer?

...that's the link for using tmax100 along with tmaxRS developer. It mentions a stock dilution. I've heard a lot about 1+9 with this developer, and while the chart mentions 1+9, I don't think that's what I'm looking for. If I have my plastic bottle (~757mL) which includes Part B and Part A, and I want to make the "stock" dilution, do I mix this A+B mix 1+9 with water? I don't want to mix the whole thing in one big gallon jug and would rather mix it from the smaller bottle as I need it. Then I just would be disposing of the used developer after each use.
Thanks!

Yes, once you mix A+B, you dilute it to the working solution, which is commonly 1:9. Just mix as needed...
Re: TMax RS developer as "one-shot"
Humm. I've used a tiny graduated cylinder to measure a few ml of part B and mix smaller amounts of working solution when needed. It would be a LOT easier to just dump the little bottle of B (I bought the gallon size so it has 15ml I think of B) into the A bottle and mix. I figured if they were packed separately there was a reason and this would probably negatively impact storage life. Does it keep pretty well if I do this? I'm sure it would be better than mixing the total gallon, of course.

Andrew,
T-Max rs mixing instructions are naturally misleading, but I might have a simple answer for you. Once you mix A+B w/ water per Kodak’s instructions, you’ve created both your 1:9 “working” solution, and/or your 1:9 “stock” solution. I should repeat that: it’s both, and you can use it either way.
Depending on your work habits, you may wish to “mix from concentrate” each session; alternatively, you might mix some for stocking. If for stocking, the next time you need it, you’d simply pull it from the shelf and use it immediately as your 1:9 working solution. No mixing required – that is, unless you want to dilute it further – for example, for compensation effects…
Many people use T-Max rs as a one-shot solution. That is, at the beginning of each session, they mix the appropriate amount directly from the concentrate, or from their stock solution. They might want 1:9, or they might want greater dilution. But in every case, once they’re done, they dispose of the solution. It doesn’t get replenished.
Me, I make stock solutions and use Kodak’s “replenishment” process.
Good for the environment!
Re: TMax RS developer as "one-shot"
I mix A & B together when I open the container and have never had a problem with shelf life. It is my understanding that they are shipped apart because some uses are better without the additive. I mix for each batch of film and discard after each use. It is the way I was taught to achieve the best consistency.
Re: TMax RS developer as "one-shot"
I use it one-shot for very critical color separation work with TMax films, where there
must be absolute repeatability and virtually no fog whatsoever.
Re: TMax RS developer as "one-shot"
With TMAX RS, simply pour the small container into the large container. When you are ready to process, just mix 1:7 or whatever proportion you choose.

Awesome! I never saw the dichroic fog from the regular stuff but always seemed to get nicer results with RS. I can dispense with the little graduated cylinder. Even if it is cool to be able to measure accurately down to a half milliliter, it's still fiddly!

BTW, T-Max 100 + T-Max rs is my “desert island” film/dev combination. ;)
If this combo ever disappeared from the film market, it would be as painful to me as the demise of Polaroid Type 55. I might not be able to survive that kind of blow again!
If you can, be sure to come back & share scans of your film development results, no matter which mixing ratio you use. I’m sure everyone will enjoy the smooth-silky “feel” of your images.

So Freeystyle sells Tmax RS "to make 1 gallon". Does that mean it makes 1 gallon, which you can dilute 1:9, or does that mean it makes 1 gallon even after it's been diluted 1:9?
It's like $13, so if that only makes 1 gallon of working solution, that's a pretty expensive developer to use 1-shot.
