The albumen silver print is a photographic printing process that was widely used in the 19th century. It involves coating paper support with a mixture of egg whites and salt, which creates a glossy surface to hold light-sensitive silver salts. The paper is then sensitized in a solution of silver nitrate, and exposed in a camera or under a negative. After exposure, the print is developed in a solution of gallic acid and silver nitrate, which reduces the silver salts to metallic silver and creates the final image. The albumen print process was widely used for commercial and fine art photography in the 19th century and produced high-quality, detailed images with a distinctive glossy finish.
André-Adolphe-Eugène Disdéri (1819-1889) was a French photographer who pioneered the carte de visite, a small photographic print mounted on a card. He is credited with popularising this format, which became widespread in the mid-19th century and had a significant impact on portrait photography and mass communication. Disdéri's innovation made portrait photography more affordable and accessible to the general public, facilitating the exchange of portraits between friends, family and public figures. His work played a crucial role in the development of photography as both an art form and a means of social documentation.
