This technique was first used in photocopying by British scientist John Herschel in 1842. Later, British botanist Anna Atkins used this technique to make plant specimens, and published the first blue-photographic collection "Photographs of British Algae: Cyanotype Impressions. At the end of the 19th century, the rapid and low-cost characteristics of the blue drying technique became the mainstream of documenting life and plants at that time. Although blue sun is no longer the mainstream of photos, its Prussian blue is still unmatched by digital photos. https://live.staticflickr.com/65535/51375899629_5378437ab9_z.jpg **｜Notes｜** 1.
