| This illustration shows the mechanism of a professional 35-mm motion-picture film camera. Most film cameras work with 35-mm film (so-called because the film image is 35-mm wide), although 16 mm or its widescreen equivalent Super 16 mm are also used, mostly for television and documentaries. For even better quality, 70-mm film may be used. A film camera works in basically the same way as an ordinary camera used to take still photographs. However, a film camera needs to take many more pictures in rapid succession and requires a far greater amount of film. It therefore needs a larger magazine to hold the film and a specially adapted mechanism to allow film to feed through. |
