20 PRACTICAL CINEMATOGRAPHY two difficulties prevent its immediate realisation. An increase of only four pictures per second represents an increase of 25 per cent, in the con- sumption of the film, and therefore in its cost. The other difficulty is more serious. Existing apparatus, both cameras and projectors, are geared to eight pictures per turn of the handle. This involves two complete revolutions per second. Consequently the gearing of the mechanism would have to be altered, and this is a more trouble- some question than appears at first sight. Some time may elapse before a forward step is taken in this direction. In matters of this character the cinematograph industry is notoriously con- servative, although the moment one firm courage- ously adopts an accelerated speed, the higher quality of the resulting pictures will force the others to follow the example. As a matter of fact the decision to adopt sixteen pictures per second was taken somewhat hap- hazardly without any scientific investigation. When it became standardised, film was expensive. Accordingly, efforts were made to secure the requisite effect with the minimum expenditure of film. Machines were built to coincide with these requirements, and the original designs have been followed slavishly in their broad outlines ever since.
