With this scientific kit, discover the Cyanotype technique, this ancestral art of monochrome photography!
This photographic process uses a mixture that reacts to light, causing the exposed areas to appear in Prussian blue. You can use the included adhesive stencils for your creations, or create beautiful pictures with dried flowers and leaves. The included frame will allow you to display your most beautiful creation!
A brief history of Cyanotype
Cyanotype is a photographic process that produces prints or images in a dark blue color known as Prussian blue. The process takes its name from the Greek word "kyanos," meaning "dark blue," in reference to this characteristic color.
This technique is linked to the effect of light on a mixture of two chemicals: ferric ammonium citrate and potassium ferricyanide . In the presence of light energy, the mixture oxidizes in air and turns blue. This technique was discovered in 1842 by the English astronomer and chemist John Frederick Herschel during his research on the effects of light. Today the cyan blue used by printers is this: 100% Cyan.
Despite its speed and simplicity, the cyanotype process never achieved widespread popularity, but it was used by the botanist Anna Atkins to reproduce tiny plants that were difficult to draw. Her herbarium, entirely composed of cyanotype reproductions of algae, " Photographs of British Algae: Cyanotype Impressions, " is considered the first published photographic book! Only about twenty copies are known to exist worldwide, each print made by Anna Atkins herself. Today, cyanotype is primarily used for artistic and educational purposes, and some contemporary artists create beautiful paintings with it.
