Photogenic drawing by William Henry Fox Talbot (1800-1877). Photogenic drawing was Fox Talbot's name for the results of his first, camerales photographic proces and derived from experiments he began in 1834 but did not announce until 1839. To produce a photogenic drawing Fox Talbot placed objects or leaves on sensitized paper. The areas where sunlight fell became darkened, while covered areas remained light. This resulted in a printed out negative image.
