daguerreotype, first successful form of photography, named for Louis-Jacques-Mandé Daguerre of France, who invented the technique in collaboration with Nicéphore Niépce in the 1830s. Daguerre and Niépce found that if a copper plate coated with silver iodide was exposed to light in a camera, then fumed with mercury vapour and fixed (made permanent) by a solution of common salt, a permanent image would be formed. A great number of daguerreotypes, especially portraits, were made in the mid-19th century; the technique was supplanted by the wet collodion process.
