The inventor of the photographic process in which a photograph produced without a negative by exposing objects to light on light sensitive paper, is named Man Ray.
Cameras and the photographic process continued to develop in rapid succession after the first camera invented. The dry plate process in 1855 made it possible for photographers to take candid photos quickly. In 1885, Kodak developed paper film.
