Come on down the rabbit hole, we have cake and everything thanks for the link, I know you can tea stain cyanotypes but never thought about using coffee lol worth a try, the sodium thiosulphate is an old school fixer. Does seem a bit of a waste of coffee though lol :P although this is still contact printing method, but seems slightly quicker than a cyanotype.
Mr. Nanian is actually the coffee expert. I've developed film using coffee before, but I haven't done it for years. Heh.
No idea what's going to happen next, but I'm hoping it involves being wrist deep in chemicals come the weekend.
