I'm moving down to Melbs soon.
I'm currently working on a colour developer (for colour negs, but it could be used in an "E-6" process as the colour dev substitute step).
If anyone already processes colour, or is set up to process b&w at home in hand tanks or whatever, I would like a couple of people to give a free sample to, or anyone that wants to register interest.
So far it looks like it'll come in 2 parts.
And the working dilutions are planned to be 1+1+50/1:1:50, and x+1+100/1:1:100 etc (Part A may be more or less than 1 for x in that ratio to get the correct pH level, I'll figure it out when I get to that testing level), like Rodinal dilutions, I'm also working on making it compatible as a split bath developer, by making it dilutable like this while maintaining quality, you can make it both economical and one shot, and eliminate unnecessary components adding to economy.
Also... because of its one-shot nature, there is a supermarket chemical you can add to the developer (that slowly kills it - not appropriate for reusing developer) that increases saturation
So you use 1+y of Part A for first bath, 1+z of Part B for second bath.
I don't think I can make a good quality colour negative developer at 20c, all my experiments show thin denisty range (dMax - dMin) even if dMax is good. There are a few experiments left to try, but I'm not entirely optimistic, I've only found one way to process colour negs at 20c to a good quality.
Anyway it'd be 30c+
