The camera lucida, which was patented in 1806, is an optical device often used by artists to sketch a subject. It superimposes an image on the drawing surface allowing faithful rendering of the subject by the artist. It is reported that the pioneering photographer, Fox Talbot, tried his hand at using the camera lucida in 1833 but was unhappy with the result. This encouraged him to seek a means to "cause these natural images to imprint themselves durably"...
