The document summarizes the early history of photography from its invention in the 1820s to its emergence as a widespread commercial technology in the late 1800s. It describes Nicéphore Niépce creating the first permanent photograph in 1826 and Louis Daguerre inventing the daguerreotype process in 1839, which produced direct positive images on silver-coated plates and did not require negatives. Daguerre's process became commercially successful and brought portraits to the masses. William Henry Fox Talbot later invented the calotype process, which used negatives to make multiple prints. Further developments including the collodion process and gelatin dry plates made photography more practical and eventually enabled photojournalism in newspapers.
