I wonder if Kodak's Ascorbic Acid-Based XTOL Developer was inspired by this idea.

  Xtol was created in 1996, making it the last really new developer. My understanding is that one of the design goals was to make a developer that was less toxic, and that ascorbic acid was part of it. I wish they still sold it in 1 liter increments. The current package makes 5 liters which means its hard for me to use before it goes bad.

    Can you separate the two powder packets by weight into 5 parts?

      Yes. I like to weight it out on a digital scale and make 2.5 liter batches. Seal the bag of unused powder with tape.

      Generally it's better to avoid doing this, because you're unlikely to get a even split of the ingredients in each packet.

    It has lasted 2 years for me if done with distilled water and stored in soda bottles with no air.
