Cecil Hepworth Robert W. Paul multiple exposures Scrooge, or, Marley's Ghost slow motion film multiple exposure
Both Cecil Hepworth and Robert W. Paul experimented with the use of different camera techniques in their films. Paul's 'Cinematograph Camera No. 1' of 1895 was the first camera to feature reverse-cranking, which allowed the same film footage to be exposed several times, thereby creating multiple exposures. This technique was first used in his 1901 film Scrooge, or, Marley's Ghost. Both filmmakers experimented with the speeds of the camera to generate new effects. Paul shot scenes from On a Runaway Motor Car through Piccadilly Circus (1899) by cranking the camera apparatus very slowly. When the film was projected at the usual 16 frames per second, the scenery appeared to be passing at great speed. Hepworth used the opposite effect in The Indian Chief and the Seidlitz Powder (1901). The Chief's movements are sped up by cranking the camera much faster than 16 frames per second, producing what modern audiences would call a "slow motion" effect.
