This is a cyanotype photogram... I made it by sensatizing a piece of chromatography paper, letting it dry, and then holding my paw over it in the sun for about a minute, then processing it.

Chromatography paper is wonderfully free of contaminates, but its basicly a sponge. This probably used 10 sheets worh of the sensitizing solution, and thats after wringing it out with a roller.
