Aquatint etching

Aquatint etching, see also "aquatint" is a printmaking process by means of which half tones can be created by surface etching. Prints made by the aquatint process are so painterly that they resemble ink drawings washed with watercolor. The technical process used in aquatinting, which is an intaglio process, was invented between 1765-1769 by Jean-Baptiste LePrince and used by artists such as Francisco de Goya and Joan Miró.
