And got the following answer:
Louis Jacques Daguerre and Joseph Nicéphore Niépce (who was Daguerre's partner, but died before their invention was completed) invented the first practical photographic method, which was named the daguerreotype, in 1836. Daguerre coated a copper plate with silver, then treated it with iodine vapour to make it sensitive to light. The image was developed by mercury vapor and fixed with a strong solution of ordinary salt. William Fox Talbot perfected a different process, the calotype, in 1840. Both used cameras that were little different from Zahn's model, with a sensitized plate or sheet of paper placed in front of the viewing screen to record the image. Focusing was generally via sliding boxes. Collodion dry plates had been available since 1855, thanks to the work of Désiré van Monckhoven, but it was not until the invention of the gelatine dry plate in 1871 by Richard Leach Maddox that they rivaled wet plates in speed and quality. Also, for the first time, cameras could be made small enough to be hand-held, or even concealed. There was a proliferation of various designs, from single- and twin-lens reflexes to large and bulky field cameras, handheld cameras, and even cameras disguised as pocket watches, hats, or other objects. The shortened exposure times that made candid photography possible also necessitated another innovation, the mechanical shutter. The very first shutters were separate accessories, though built-in shutters were common by the turn of the century. The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloid in 1889. His first camera, which he called the "Kodak," was first offered for sale in 1888. It was a very simple box camera with a fixed-focus lens and single shutter speed, which along with its relatively low price appealed to the average consumer. The Kodak came preloaded with enough film for 100 exposures and needed to be sent back to the factory for processing and reloading when the roll was finished. By the end of the 19th century Eastman had expanded his lineup to several models including both box and folding cameras.
