Long before digital sensors and instant smartphone cameras, capturing an image was a complex chemical dance. Today, one of the most popular and accessible ways to experience the magic of early photography is through sun printing, or "cyanotype." It is a beautiful craft that sits perfectly at the intersection of our Arts & Crafts and Tech & Maker collections. But how did this brilliant blue photographic process begin?

Sir John Herschel and the First "Blueprint" The cyanotype process was invented in 1842 by Sir John Herschel, a brilliant English astronomer and scientist. Herschel was looking for a way to easily reproduce his complex mathematical notes and astronomical diagrams. By treating paper with a mixture of iron compounds (potassium ferricyanide and ferric ammonium citrate) and exposing it to sunlight, he discovered he could create a permanent, beautiful cyan-blue image. This practical invention became the original "blueprint," a method used by architects and engineers for over a century.

Anna Atkins: The First Female Photographer While Herschel invented the process for practical reproduction, it was a botanist named Anna Atkins who realized its artistic potential. In 1843, Atkins placed various algae and fern specimens directly onto cyanotype paper and exposed them to the British sun. The result was Photographs of British Algae: Cyanotype Impressions—recognized today as the very first book entirely illustrated with photographs. Atkins effectively became the first female photographer in history.

Harnessing the Sun Today Today, you do not need to be a 19th-century chemist to create sun prints. Modern cyanotype kits allow you to use leaves from your garden, pressed flowers, or even household lace to create stunning, one-of-a-kind blue and white botanical art. It is a magical, family-friendly hobby that teaches the fundamentals of light and chemistry while producing frame-worthy home decor.
