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 had begun in 1834 but did not announce until 1839. To produce a photogenic drawing Fox Talbot placed objects or leaves on sensitized paper - areas where sunlight fell darkened, covered areas remained light, resulting in a printed out negative image.
