The document traces the origins and early development of photography from the camera obscura through its evolution into a portable box form. It describes some of the key early inventors and photographic processes including Joseph Nicéphore Nièpce's "first photograph" from 1826, the daguerreotype process developed by Nièpce and Daguerre, and the calotype process invented by William Henry Fox Talbot which produced negatives allowing for multiple prints. The document also discusses how photography became more widely available commercially in the mid-19th century through portrait studios and the rise of cartes de visite photographs.
