Frederick Scott Archer's wet collodion process, announced in 1851, became the standard photographic negative process for both amateurs and professionals from the mid-1850s until the early 1880s.
In 1840, Talbot invented the calotype process, which, like Daguerre's process, used the principle of chemical development of a faint or invisible latent image to reduce the exposure time to a few minutes. Paper with a coating of silver iodide was exposed in the camera and developed into a translucent negative image.
