I have been inspired by the rich blue designs Cyanotype gives. It feels like alchemy; mixing water with potassium ferricyanide and ferric ammonium citrate, painting it on card and leaving to dry in a dark room. These are then taken outside into the bright sun with a filter (be it an object, photo negative or drawing) and allow the sun the activate the chemical reaction. Taking it back inside to rinse off the un-activated portion creates these stunning prints. Finally as they dry the react with the oxygen in the air and finish a brilliant cobalt blue.
