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.
NicÃ©phore NiÃ©pce invented the first camera, which was a pair of nested boxes using light sensitive paper. It was modified and successfully made into a commercial product by his associate Louis-Jacques-MandÃ© Daguerre as the Daguerreotype.
