technique used by the French etchers in the 19th century, by such artists as Corot and Daubigney.
First employed by WHFT in 1834 (without being named) but commonly associated with French artists of the 1850s and later. A negative was created manually by scratching through an opaque varnish layer coated on glass. This was then printed on light-sensitive photographic paper to make multiple final prints.
An autographic process where a glass plate is covered in a dark emulsion. A stylus is used to draw an image leaving the bare glass where light can pass through. Photographic paper is used and the print is developed in the usual way. Favored by Corot and Millet.
A photographic print produced from a hand-drawn negative.
