I tried replacing the ammonium fix with hypo, I did the math to equal the thiosulfates out (granted the hypo wasn't exhausted) but the fix wasn't fast enough to stop the Dektol in time, so I got a negative image on the plate. Thou, the thin areas where toned a varying green to orange color. I think I'm going to an iron sulphate developer next, because I never cared for the green-yellow hue I got with the Dektol/ammonium developer.

Oh, and a correction to my previous post, I used 4oz stock dektol, not 2oz.
