Twenty-five milliliters of freshly mixed platinum solution. I'm printing a new set of small Pt/Pd prints from a picture series made over the past couple months in forest parks and preserves here in Connecticut.
Also, I'll be teaching my "digital platinum" workshop this coming weekend at The Penumbra Foundation in NYC—I understand there are a couple places left.
Here are iPhone snaps of this morning's four prints in the clearing baths.
