Glass plate collodion negatives used to make prints on albumen paper soon became the preferred photographic method and held that position for many years, even after the introduction of the more convenient gelatin process in 1871. By the end of the 1850s the daguerreotype had been replaced by the less expensive and more easily viewed ambrotype and tintype, which made use of the recently introduced collodion process. Inventors set about working out improved processes that would be more practical. Each was a unique opaque positive that could only be duplicated by copying it with a camera. The daguerreotype had shortcomings, notably the fragility of the mirror-like image surface and the particular viewing conditions required to see the image properly. Other inventors soon made improvements which reduced the required exposure time from a few minutes to a few seconds, making portrait photography truly practical and widely popular.
Its existence was announced to the world on 7 January 1839 but working details were not made public until 19 August. He named this first practical process for making photographs with a camera the daguerreotype, after himself. He exposed a silver-plated copper sheet to iodine vapor, creating a layer of light-sensitive silver iodide exposed it in the camera for a few minutes developed the resulting invisible latent image to visibility with mercury fumes then bathed the plate in a hot salt solution to remove the remaining silver iodide, making the results light-fast.
