Albumen Print

The albumen print, invented in 1850 by Louis Désiré Blanquart-Evrard, was the first method of producing a print on paper from a negative. It used the albumen found in egg whites to bind the photographic chemicals to the paper and became the dominant form of photographic positives from 1855 to the turn of the century. During the mid-1800's, the Carte de visite was one of the most popular forms of this type of printing process.
