THE FUTURE 365
ments in connection with a wide screen and has perfected a camera and a projector to accomplish his end. It appears that the wide film eliminates distortion. Furthermore, this type of picture presents new opportunities in effects and photographic values. Such apparatus must not be confused with the magnified screen attained by use of a magnifying lens, as employed in projecting certain scenes of Wings, The Big Parade, and other great film creations.
The time may come, and that in the near future, when the screen itself will be the loudspeaker, eliminating the necessity of horns, dynamic cones, or any of the present equipment used for the purpose. Experiments along such lines have already been undertaken by one of the important laboratories. Another effort that has been made is to devise an instrument through which it may be possible to replace or substitute a voice on talking picture films. With such a process it may be possible to revocalize American-made films for foreign languages, very possibly a great aid in catering to the market abroad. This device would also permit utilizing the voice of a gifted player for other performers good in screen personality but deficient in vocal quality.
It may be expected that in due time and with the development of cameras free from objectionable mechanical noises, the so-called camera "tanks" will be eliminated. Already important experiments have been conducted by several of the studios looking to the improvement of "shooting" scenes by substituting the use of the portable tank. Some success in this direction has been achieved by placing a portable box over the camera; the box having the effect of muffling the clicking of the mechanism. The camera is mounted on a tripod, as heretofore, and a housing of soundproof materials encloses the camera box.
The highest technical perfection, however — stereoscopics, or the third dimension — is still lacking, although
