Auguste François Willème invented the process known as photosculpture in the early 1860s to produce three-dimensional portraits with the ease of photographic cartes de visite. The client—here, well-known actress Rose Deschamps—posed in the center of a circular room and was photographed simultaneously by twenty-four miniature cameras. Lantern slides of these images were then projected onto a clay cylinder while one worker traced the silhouette and another cut it into the clay. Other workers would then model subtle details, and the object would be rendered in a more stable material, such as earthenware or porcelain. The process proved too labor-intensive to be profitable, and Willème's studio went out of business in 1868.
