Thomas Wedgwood
Wedgwood first used ceramic pots coated with silver nitrate as well as treated paper and white leather as media of print, and had the most success with the white leather. Although he originally tried to create images with a “camera obscura,” his attempts were unsuccessful. His major achievements were the printing of an object’s profile through direct contact with the treated paper, thus creating an image’s shape on paper, and, by a similar method, copying transparent paintings-on-glass through direct contact and exposure to sunlight.
