An albumen print is a type of photographic print made from a negative on which a layer of egg white, specifically egg albumen, is used as the binder for light-sensitive materials. It was a popular photographic process during the 19th century, particularly from the 1850s to the 1890s.The albumen print process begins with coating a sheet of paper with a solution made from egg whites mixed with salt. Once the coating dries, the paper is sensitized by immersing it in a solution containing silver nitrate. This sensitized paper is then exposed to light through a negative, resulting in a latent image.After exposure, the paper is developed using a developer solution, typically gallic acid or pyrogallic acid, which converts the exposed silver salts into metallic silver. The image is then fixed to remove any unexposed silver salts, making it permanent and stable.Albumen prints are known for their tonal range, sharpness, and fine detail. The use of egg albumen as the binder gives the print a glossy surface and helps to hold the light-sensitive materials in place, enhancing the image's clarity and definition.In terms of aesthetics, albumen prints often have warm tones, with a range of brown, sepia, or purple hues. The process was commonly used for portrait photography, as well as landscape, architectural, and documentary photography during the 19th century.Albumen prints played a significant role in the history of photography, serving as a precursor to later photographic processes. They are appreciated today for their historical value and the unique aesthetic qualities they impart, providing a glimpse into the early days of photography and the artistry of the era.
