One for the Pt/Pd obsessives... What's the highest Dmax you can consistently achieve with your platinum/palladium prints? I can get to about 1.39 with a 2:1 mix of Pt and Pd, and I think I can probably squeeze out a few more ounces of black now that I've built a new printing rig. (Paper white for my paper is about 0.12 if that's relevant.) That's a pretty convincing black, but I suspect blacker blacks are possible. What's your blackest Pt/Pd black?
