First successful form of photography.It is named for Louis Daguerre, who invented the technique in collaboration with Nicéphore Niepce. They 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. The first daguerreotype image was produced in 1837, by which time Niepce had died, so the process was named for Daguerre. Many daguerreotypes, especially portraits, were made in the mid 19th century; the technique was gradually replaced by the wet collodion process, introduced in 1851.* * *
first successful form of photography, named for Louis-Jacques-Mandé Daguerre (Daguerre, Louis-Jacques-Mandé) of France, who invented the technique in collaboration with Nicéphore Niépce (Niépce, Nicéphore) 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.* * *
