History of the camera shutter. The very first shutters were separate accessories, though built-in shutters were common by the end of the 19th century. The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloid in 1888-1889. His first camera, which he called the "Kodak," was first offered for sale in 1888. It was a very simple box camera with a fixed-focus lens and single shutter speed, which along with its relatively low price appealed to the average consumer. The Kodak came pre-loaded with enough film for 100 exposures and needed to be sent
Kodak DCS 300 series cameras had different sized CCD imaging chips, both of which were smaller than either 135 film or APS-C film frames. The 315's imager had a crop factor of 2.6 relative to 135 film ("35mm"), while the 330's was larger with a factor of 1.9. The Kodak modification to the Pronea 6i involved removing the camera's film back and mounting instead a Kodak digital back. This not only covered the back of the camera, but also extended beneath it, approximately doubling the camera's height. This was required to accommodate the large PC cards used as storage media, the six AA batteries
