Sep 27, 2024 · On September 21–23, 1840, while experimenting with gallic acid, a chemical he was informed would increase the sensitivity of his prepared paper, Talbot discovered that the acid could be used to develop a latent image. This discovery revolutionized photography on paper as it had revolutionized photography on metal in 1835.
A Brief History of Photography. Because images are such an important part of the Authentic History Center, this section was created to give very brief descriptions of the evolution of photograph technology, accompanied by examples of each technology. DAGUERREOTYPE: 1839-1860s.
The history of photography began with the discovery of two critical principles: The first is camera obscura image projection, the second is the discovery that some substances are visibly altered by exposure to light. [2]

The descriptions above do not indicate the complexity of the chemical processes. Many people with an interest in chemistry struggled with different combinations of chemicals to find practical methods of creating successful images and obtaining a positive image from the negative. In England, the first person to succeed in this whole process was Will...
Others continued to try to find different methods of creating photographs. An important method known as the cyanotype was developed by Herschel, in 1842. The process uses a mixture of two chemicals, ferric ammonium citrate and potassium ferricyanide. The prints, which are blue in colour, can be fixed by washing in plain water. (There are variants o...
This was apparently invented almost simultaneously by Frederick Scott Archer and Gustave Le Gray. This process used a prepared glass plate which, in the darkroom, would be coated with collodion (a highly flammable solution of nitrocellulose, ether, and alcohol). It was then made light-sensitive with further chemicals and before it could dry, was pl...
Richard Leach Maddox invented the gelatin dry plate silver bromide process. This led to the invention of dry plate photography, which did not require the photographer to develop the plate immediately after exposure. This proved to be a highly successful process, which continued to be used into the 1920s.
In 1885, George Eastman started manufacturing flexible, paper-based photographic film. Although convenient, it produced rather poor results. In 1887 Reverend Hannibal Goodwin filed a patent for celluloid photographic film. The patent was not granted until 1898. In the meantime, George Eastman had already started production of this type of film usin...
Thomas Eakins. Department of Photographs, The Metropolitan Museum of Art. October 2004. In the 1880s, through a series of technical advances that greatly simplified its practice, photography had expanded from being the province solely of the specialist into an activity accessible to the millions.
1826: Nicéphore Niépce takes the first surviving permanent photograph. 1839: Invention of the daguerreotype by Louis Jacques Mandé Daguerre is announced in Paris. The first publicly announced photographic process, the daguerreotype yielded unique and exquisitely detailed images.
