;8 PRACTICAL CINEMATOGRAPHY the film as soon as possible after exposure. Although the exposed film is kept in a dark box, the chemical action set up by exposure before the lens, continues, as in dry-plate and snap-shot photography, and in a more rapid manner. Consequently the film should not be left undeveloped for more than a few days at the utmost. While prompt development is usual in topical work, there are other sorts of work in which the operator may feel tempted to put the film on one side for development at a later and more convenient time. Perhaps several weeks may elapse, and then complete amazement is expressed at the result. In the unexposed condition, however, Eastman stock will last many months so long as it is not removed from the case in which it is packed at the works. Equal care must be used in storing the developed negative films. They must be kept in a cool dry place, protected from severe fluctuations in temperature and climatic effects.
