On December 6, 1850, a significant event in the history of photography took place. French physicist and inventor Louis-Désiré Blanquart-Evrard introduced the albumen print process to the French Academy of Sciences. This groundbreaking technique revolutionized the world of photography and remained the dominant form of photographic printing for nearly three decades.
The albumen print process involved coating paper with a layer of egg white (albumen) mixed with salt, which was then sensitized with a solution of silver nitrate. This created a light-sensitive surface that could capture incredibly detailed images when exposed to light through a negative.
Blanquart-Evrard's invention greatly improved upon earlier photographic printing methods, such as the calotype and daguerreotype. Albumen prints offered higher resolution, greater clarity, and a wider tonal range than previous techniques. The process also allowed for the mass production of photographic prints, making photography more accessible to the general public.
The albumen print process quickly gained popularity among photographers worldwide. It was used extensively for portraiture, landscape photography, and documentary purposes. Many iconic images from the mid-to-late 19th century, such as photographs of the American Civil War and the exploration of the American West, were captured using this technique.
Blanquart-Evrard's contribution to the field of photography cannot be overstated. His invention paved the way for the development of even more advanced photographic technologies and helped establish photography as a legitimate art form and means of visual communication. The albumen print process remained in use until the 1890s when it was gradually replaced by newer techniques like the gelatin silver print.
So, the next time you look at an old photograph from the 19th century, there's a good chance it was created using the albumen print process, thanks to the innovative work of Louis-Désiré Blanquart-Evrard on this day in 1850.
