FWIW, when I was doing kallitypes, palladium was maybe half the price of
platinum, and I toned them with palladium. Color was a very beautiful deep
rich black.
I think palladium costs as much as platinum now, doesn't it, or is that
just rumor?
But I wonder about your mention of hypo eliminator. Last I heard (long
ago, admittedly) experts said don't use that, bad for SG prints. Is that
now inoperative?
