George Eastman George Eastman George Eastman (July 12, 1854 – March 14, 1932) was an American entrepreneur who founded the Eastman Kodak Company and popularized the use of roll film, helping to bring photography to the mainstream. Roll film was also the basis for the invention of motion picture film stock in 1888 by the world's first film-makers Eadweard Muybridge and Louis Le Prince, and a few years later by their followers Léon Bouly, William Kennedy Dickson, Thomas Edison, the Lumière Brothers, and Georges Méliès. He was a major philanthropist, establishing the Eastman School of Music, and schools of dentistry and medicine
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
