Ah i never realised it could be used as an ACTUAL developing agent, I might give that a try, I don't reckon it would last long once mixed? like rodinal as Vitamin C is unstable Also, what about using a salt of ascorbic acid, such as sodium ascorbate? does it require the molecule ascorbic acid on its own or can it still do its action, bound to the sodium? Also what about ascorbic acid esters? I always knew sodium ascorbate to be more stable, at least I think it is...
