An example when photography looks like its made in the etching technique

Etching

Etching is a method of making prints from a metal plate, usually copper or zinc, which has been bitten with acid. The plate is first coated with an acid-resistant substance (etching ground or varnish) through which the design is drawn with a sharp tool (burin or other). The acid eats the plate through the exposed lines; the more time the plate is left in the acid, the coarser the lines. When the plate is inked and its surface rubbed clean, and it is covered with paper and passed under a cylindrical press, the ink captured in the lines is transferred to the paper.

The first etching on record was that of the Swiss artist, Urs Graf, who printed from iron plates. Albrecht Dürer, though a consummate engraver, made only five etchings, and never really dominated the technique. That was left to later artists like the Italian Parmigianino and, of course, Rembrandt, perhaps the greatest etcher of all time... Later adepts of acid etching were Tiepolo and Canaletto in Italy and, of course, Francisco Goya in Spain. The 20th century saw important bodies of work by Pablo Picasso, Henri Matisse, Marc Chagall and Georges Rouault.
