The cyanotype process, also known as the blueprint process, was first introduced by John Herschel in 1842. The cyanotype is made up of two simple solutions which are Solution A: 25 grams Ferric ammonium citrate (green) and 100 ml. water. Solution B: 10 grams Potassium ferricyanide and 100 ml. the cyanotype was mainly used for blueprints and people used them to produce low quality images or drawings. The steps I used to create the negative was i went into photoshop and I first changed it to black and white and i adjusted the brightness and contrast. From there I inverted and then printed it out. To create the actual cyanotype i spread the solution onto the paper and i made sure it was dry enough. After that I put my negative face up and i out the glass on top. I let it sit outside for quite a while. After that i put it in the water to wash out the yellow and after that I put it in the peroxide for a minute or so and then I let it dry.
