Early movie cameras were fastened to the head of their tripod with only simple levelling devices provided. These cameras were thus effectively fixed during the course of the shot, and hence the first camera movements were the result of mounting a camera on a moving vehicle. The Lumière brothers shot a scene from the back of a train in 1896.
The first rotating camera for taking panning shots was built by Robert W. Paul in 1897, on the occasion of Queen Victoria's Diamond Jubilee. He used his camera to shoot the procession in one shot. His device had the camera mounted on a vertical axis that could be rotated by a worm gear driven by turning a crank handle, and Paul put it on general sale the next year. Shots taken using such a "panning" head were also referred to as ‘panoramas’ in the film catalogues of the first decade of the cinema.[5]
Georges Méliès built one of the first film studios in May 1897. It had a glass roof and three glass walls constructed after the model of large studios for still photography, and it was fitted with thin cotton cloths that could be stretched below the roof to diffuse the direct rays of the sun on sunny days.[6]
The Execution of Mary Stuart, produced by the Edison Company for viewing with the Kinetoscope, showed Mary Queen of Scots being executed in full view of the camera. The effect was achieved by replacing the actor with a dummy for the final shot.[7] Georges Méliès also utilized this technique in the making of Escamotage d’un dame chez Robert-Houdin (The Vanishing Lady). The woman is seen to vanish through the use of stop motion techniques.

The other basic technique for trick cinematography was the double exposure of the film in the camera. This was pioneered by George Albert Smith in July 1898 in England. The set was draped in black, and after the main shot, the negative was re-exposed to the overlaid scene. His The Corsican Brothers was described in the catalogue of the Warwick Trading Company in 1900: “By extremely careful photography the ghost appears *quite transparent*. After indicating that he has been killed by a sword-thrust, and appealing for vengeance, he disappears. A ‘vision’ then appears showing the fatal duel in the snow.”
G.A. Smith also initiated the special effects technique of reverse motion. He did this by repeating the action a second time, while filming it with an inverted camera, and then joining the tail of the second negative to that of the first.[8] The first films made using this device were Tipsy, Topsy, Turvy and The Awkward Sign Painter. The earliest surviving example of this technique is Smith's The House That Jack Built, made before September 1900.
Cecil Hepworth took this technique further, by printing the negative of the forwards motion backwards frame by frame, so producing a print in which the original action was exactly reversed. To do this he built a special printer in which the negative running through a projector was projected into the gate of a camera through a special lens giving a same-size image. This arrangement came to be called a “projection printer”, and eventually an “optical printer”.
The use of different camera speeds also appeared around 1900 in the films of Robert W. Paul and Hepworth. Paul shot scenes from On a Runaway Motor Car through Piccadilly Circus (1899) with the camera turning 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. This gives what we would call a “slow motion” effect.
