Who invented photography?

The first true photographs, exposed on metal that had been sensitized to accept an image, were named for their French inventor L. J. M Daguerre in 1837.
The inventor of the first process, which used a negative from which multiple prints were made, was William Henry Fox Talbot, a contemporary of Daguerre.
Tintypes, patented in 1856 by Hamilton Smith, were another medium that heralded the birth of photography. A thin sheet of iron was used to provide a base for light-sensitive material, yielding a positive image. Photography advanced considerably when sensitized materials could be coated on glass plate. The first glass negatives were wet plate. They had to be developed quickly before the emulsion dried. In 1889, George Eastman, realizing the potential of the mass market, used a newly invented film with a base that was flexible, unbreakable and could be rolled. Emulsions coated on a cellulose nitrate film base, such as Eastman’s, made the mass-produced box camera reality.
