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

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.
