To avoid violating Edison’s motion picture patents, Biograph cameras from 1895 to 1902 used a large-format film measuring 2-23/32 inches (68 mm) wide, with an image area of 2 × 2½ inches, four times that of Edison’s 35 mm format. The camera used friction feed, instead of Edison’s sprocket feed, to guide the film to the aperture. The camera itself punched a sprocket hole on each side of the frame as the film was exposed at 30 frames per second. A patent case victory in March 1902 allowed Biograph and other producers and distributors to use the less expensive 35 mm format without an Edison license, although Biograph did not completely phase out 68 mm production until autumn of 1903. Biograph offered prints in both formats to exhibitors until 1905, when it discontinued the larger format.
