The Bromoil Process was an early photographic process that was very popular with the Pictoralists during the first half of the twentieth century. The soft, paint-like qualities of the prints are very typical for this genre.
Basically, the process consists of replacing the silver image by lithographic ink. The ink application requires considerable skill, and as a result no two prints are alike. Bromoil is one of the rarest and the most permanent of the photographic printing processes.
