You don't need a camera to create a cyanotype. It essentially involves placing an object or objects onto a paper coated with iron salts, which is then exposed to either sunlight (known as a photogram) or UV light. Following the exposure, the paper is washed to produce images in Prussian blue and white. 

The scientist Sir John Herschel invented the process. It was adopted by Anna Atkins, a botanist. She used it to produce the first photographic book, Photographs of British Algae in 1843. This is in the public domain and visible on The New York Public Library Digital Collections site.
