The first flexible photographic roll film was sold by George Eastman in 1885, but this original "film '' was actually a coating on a paper base. As part of the processing, the image - bearing layer was stripped from the paper and attached to a sheet of hardened clear gelatin. The first transparent plastic roll film followed in 1889. It was made from highly flammable nitrocellulose ("celluloid ''), now usually called "nitrate film ''.
