Roll film camera (Kodak)

'You press the button, we do the rest': photography becomes something anyone can do.

George Eastman's 1888 Kodak camera came loaded with a roll for 100 exposures, returned to the factory for developing; flexible celluloid film followed in 1889. Roll film took photography to the public and supplied the strips that made motion pictures possible.
