A couple of weeks ago I did a one-day cyanotype workshop for members of my book arts group. They were very enthusiastic, and one friend in particular was keen to try more. I recommended getting the chemicals at Keeble & Shucatt, a local store that carries kits from Photographer's Formulary. But she lives over in the East Bay and she ended up getting them somewhere in Berkeley. When I asked how it went, she replied, "David and I cooked up the brew (we had to buy chemicals and cook them in the dark on the stove). It was the only solution I could find in Berkeley. Anyway.... The mid tones are great, the blue is soft and the process was easy."
Her reference to cooking the chemicals really baffled me. I've never cooked them, and have never seen anything in the literature about it-- but I admit I'm somewhat new to this myself. Is this something that is rendered un-necessary by using the Photographer's Formulary kits?
