What developments in chemical photography occurred in the nineteenth
century?

Was coined in 1839 by Sir John Herschel, who was an important contributor to the development of the discipline himself. Thomas Wedgwood tried capturing pictures on pieces of leather, calling them “sun images” – however, they faded rapidly and could not be saved permanently. However, his actions were a passage to the first successful attempt to capture an image that would not fade away - one by Nicéphore Niépce in 1826, after 10 long years of working with camera obscura and photosensitive materials. when Niépce died and Daguerre continued the practice on his own. He then began exploring the silver-based processes again, until he finally discovered that pictures could be developed to full visibility using mercury fumes, with less exposure time too, directly onto the silver plates that were fumed with iodine vapor to produce silver iodide. The image was then stabilized or “fixed” using hot solution of common salt, which removed the remaining silver iodide. It was the year 1888 when Eastman’s very first hand-held Kodak camera containing the film went on the market and became available to practically everyone.
