RE: Trivia time: room temperature solubility of platinic acid

Well, Yes. Perhaps my point missed both you and Sandy. Does the Na2 produce
prints of warmer color than prints made using Platinic Acid, where the Na is
replaced in the compound by H. Discounting the effect that PT would have on
the image tone by cooling it down a bit, and since the same amount of
platinum is in both the magical Na2 and in Platinic Acid, what then accounts
for any difference in image color?

So Clay, have you used both? What say ye?
