Jean-Baptiste-Camille Corot, a master of the painted landscape, also made landscape the subject of the great majority of his roughly one hundred prints. He worked in etching, lithography, and cliché-verre, a technique invented in the mid-nineteenth century that was a hybrid of printmaking and photography; Corot was the most prolific and the best-known practitioner of this medium. In this technique, an image is created on a glass plate by one of several means. To create the present print, the plate was coated with collodion and the image was scratched into the coating; then, the plate was immersed in acid, etching the image into it. The plate was then used as though it were a negative, to print images photographically.
