Oriental WT FB is an extremely warm paper. I've tested most papers on the market today, and Oriental's WT is almost a yellow/green in the mid tones. I think Amidol/Ansco130 are typically "cool tone" developers, but that's just what I know from what I've heard. Maybe the combination of both knocks down the "warmth" of Oriental's paper to a level pleasing to your eye. I've tried it with Ilford CT developer and it seemed to do that. Hey someone with some more background in chemistry want to tell me if there's any relevancy to this or am I just sniffing too much fix?
