16 g/l washing soda waterfree, 10 g/l Vitamin-C, 40 g/l instant coffee, 1,5 g/l potassium bromide (KBr)
Use 1 - 2 gram/liter KBr, 1,5 seems to be a good idea. Do not use more than 2 g/l, it will restrain development too much up to blank negs.
40 minutes semi-stand development at 24 °C. Agitation first minute continuos, 3 inversions each at 2, 4 and 8 minutes, then let stand.
No fog, fine grain, perfect even development, about boxspeed.
Maybe some minor tweaks in the future, but looks fine so far.
Maybe not everybody is able to get potassium bromide easily? I got it from my next door pharmacy. It's not toxic and environmentally safe with the used quantities.
Looks promising that C-C-L may also be good for high speed films.
Do not try (semi-)stand development without a restrainer like KBr -> agitation is the key!
PS: I didn't use semi-stand development for another reason than comfort, I don't like shaking for half an hour. ;-)
