Cyanotype is an early photographic process that produces blue prints. It was invented in 1842 by Sir John Herschel, and was popular in Victorian England. The chemicals needed are simple: ferric ammonium citrate and potassium ferricyanid. It’s a contact process, so positives have to be placed right over the paper. Sunlight or UV light is required for the exposure. Cyanotypes are pretty simple, and anyone can do them at home.
I thought it would be fun to make a film simulation recipe to mimic cyanotype prints. Fujifilm X-Trans IV cameras have the ability to tone black-and-white pictures, either warm or cool. By toning the pictures blue, I was able to get in the neighborhood of cyanotype photography. Unfortunately, going all the way cool, which is -9 on toning, is only marginally blue enough to pass for cyanotype. Still, this was a fun experiment. If you are bored, why not give it a try yourself?
