Century Dictionary and Cyclopedia
- n. A photographic process devised by Fox Talbot about 1840, but not now in use. In this process a reflected image is impressed on sensitized paper by exposure in a camera, developed by gallonitrate of silver, and fixed by hyposulphite of soda. The paper used is prepared by being saturated with iodide of potassium and then washed with nitrate of silver, thus forming an iodide of silver, which is rendered very sensitive to light by a wash of gallic acid and nitrate of silver.
- n. A talbotype
