"Cliche Verre is a method of etching on a ground-coated transparent material, or painting and drawing on a transparent surface, such as glass or film and printing the resulting image on a light sensitive paper. It is a process first practiced by a number of French painters during the early part of the 19th century. Camille Corot was the best known of these. Some contemporary artists have developed techniques for achieving a variety of line, tone, texture and color by experimenting with film, frosted mylar, paint and inks and a wide assortment of tools for painting, etching, scratching, rubbing and daubing."
