> You said you never kept D-76H so you didn't know. Guess what, I know it exhibits brown tint when it's going off.(posted 8323 days ago)Right; I make small quantities and it doesn't sit around long. I have, however, had a couple of occasions in which apparently it was getting a little weak, just enough to give slight underdevelopment, and I didn't see any tint change.
>I kept my XTOL stock solution in PET bottles for months with no visible change in image quality.
I had good luck with Xtol, which I always decanted into small ready-to-use quantities of stock and stored in the refrigerator, until one of those small containers turned out to be rather dead. What was odd was that the previous day I'd used another container of the same stock and it was fine. Perhaps there was an air leak, I don't know, so I'm not one of those trumpeting "Xtol failure" since it could have been pilot error.
> I haven't heared a single complaint about Ilfosol-S yet. Guessing from all these combined I think ascorbate formulae don't necessarily have to sacrifice their shelf life when properly prepared and stored.
I've seen just a couple of complaints about Ilfosol-S having an unexpectedly short storage life but since no context was given I took them with a huge grain of salt. I've had no trouble myself.
> Right now, my interest is whether ascorbate version of D-76d and buffered FX-1 really benefit from ascorbate or not.
I'm thinking of taking a look at plain D-76 and simply replacing the hydroquinone in the formula with ascorbate and comparing this with my usual D-76H. If storage is a problem it'd be easy to just add the ascorbate to the working solution.
