In this paper Talbot (1800–1877, photographer, inventor) announced his invention of the photographic process, the first permanent negative process on paper, that he called Calotype and later – first in print in the title of this paper – Talbotype. His process was the forerunner of most photographic processes of the 19th and 20th century. It also had the advantage of fastness compared to other photogenic drawing processes of the time. An extremely rare and early paper on photography, as Talbot printed privately, in limited number for presentation to his friends and editors.
