what is cyanotype? its a photographic process that produces a cyan blue print
whats the process?
choose your formula. its made of two solutions, first one being ferric ammonium citrate and water. and the second one being potassium ferricyanide and water.
mix the chemicals together. first mix them separately with water until dissolved then mix the two solutions together.
prepare the canvas. using a brush, paint the chemicals onto the paper, card or anything you can print on. make sure the area your working in is dimly lit. the leave to dry in a dark place.
printing the cyanotype. by printing the cyanotype you place your negative or object onto the coated paper or fabric. sandwich it with glass then expose that to the sunlight or a uv light.
processing and drying. when your print has been exposed your process it by washing it in cold water (washing it also removes any unwanted chemicals). wash for five minutes or until the water becomes clear.
