Jan, it's an unusual formula in that it has three developing agents. Could you explain your reasoning? Also, does it stain the negative?

[Quinine]

hi,

this formula was inspired by fx 11 (which also contains 3 dev agents) and and pyrocat hd. i tried to get best of both worlds.

this formulas seems to get most of it, so i think it will produce very good results even for push-processing. and yes, it gives some stain.

i'm trying to get some more results today evening. i'll keep you posted.

best regards, --- jan.
