THE MOVING-PICTURE CAMERA AND ITS MECHANISM
The cinematograph camera differs entirely from the instruments used in other branches of photography. While the advanced worker and the prosperous picture-play producer employ costly and elaborate machines, the amateur, or the independent worker, in the particular field which he has selected for his operations, can get equally good results with an apparatus only a fifteenth or even a twentieth part as expensive. The range of operation with the cheaper instrument may be limited, and it may be deficient in those many little refinements which are characteristic of the professional appliance, and may lack silver-plated finish and highly-polished woodwork or morocco leather covering. But the camera itself is more important than these.
The cameras, both expensive and low-priced, work upon the same fundamental principles. In the latter everything is reduced to the simplest form so as to be readily and easily understood by the beginner. They have the additional recommendation that the risk of breakdown is eliminated, because the few essential component parts are substantially made, well-proportioned, and nicely-balanced. Serviceability and reliability are the outstanding features of the low-priced camera, and it is applicable to almost every branch of the craft.
Contrary to general belief, taking the "movies" is quite as simple as snap-shot photography with a Kodak. In the latter case you press the button; in the former you turn the handle; the camera does the rest. The rotation of the handle, a simple operation, performs every duty through the internal mechanism. It swings the shutter across the lens, moves the film intermittently through the instrument, and coils up the exposed film in its dark box.
As has been explained, the beginner is now able to make his selection from a wide variety of makes, ranging in price from £5 ($25) upwards. If one desires to gain experience in the cinematographic art with the minimum capital outlay, the Jury, "New Era," or "Alpha" cameras will suit the purpose excellently. Both are first-class, well-made machines, having perfect registration and alignment, extremely simple and easy to handle. The first-named model, which is the cheapest, is contained in a mahogany case measuring 9-1/2 inches square by 4-3/4 inches deep, and in the unloaded condition weighs 5-1/2 pounds. The "Alpha," which costs a little more, is full value for money, and is well worth the slightly increased price. This camera is fitted with a light-proof hinged front panel giving access to the adjustable shutter, which permits the opening of the latter to be varied within wide limits and thus enables extremely rapid movements to be photographed while running the machine at the normal speed. The spool boxes carry 100 feet of film of standard gauge in each instance, and for general all-round work, such as the recording of topical events, either model will be found perfectly efficient. It may be mentioned that both models are supplied without the lens, because the average beginner in motion-picture work, having practised still-life or snap-shot photography, has usually developed a marked fancy for some particular make of lens--Dallmeyer, Cooke, Ross, Zeiss-Tessar, or Voigtlander. Naturally, being familiar with the working of his favourite and knowing what he can do with it, he feels more at home when he is able to have it fitted to his moving-picture machine. Here, again, there is a wide selection to meet all purses, so that the most fastidious tastes in regard to the lens may be gratified. On the other hand, if the beginner has no marked preference, and wishes to be economical, he can get a lens capable of doing first-class work at a remarkably low price. His complete outlay upon the camera and the lens need not exceed £6 5_s._, or, say, $31.
