The thinness may in part be the base, which LOOKS thin even with Technidol. But I'm not surprised by the low numbers, either. I really don't think there is a way to get better ISO out of TP. 50 is probably the highest with the best of luck in combinations. I know someone who shot at 50 and developed in XTol. It was gross.(posted 8904 days ago)I've still to do it to any large extent, but I really think TP is an ISO 12 emulsion...
