International photographer (Feb-Dec 1929)

Ten The INTERNATIONAL PHOTOGRAPHER December, 1929 the amount of footage run through the test track whether right or left and can not he run or used without affecting said counter. It is also equipped with an electromagnetic scene counter and buzzer signal enabling the operator to instantly check his progress without the costly mistake of giving the right numbers to the wrong scenes, and the buzzer is additionally provided as a warning. A set of meters is provided to indicate at all times the exact condition of the current supply, and former errors due to changing contact resistance in the rheostats have been precluded by the construction of a step by step plug and segment control such as employed by the manufacturers of precision measuring resistance boxes where the highest degree of accuracy is required. In keeping with these considerations the instrument has been machined with the precision of a standard camera movement and heavily chrome plated where subject to handling or friction. Every suggestion for fool-proofing and efficiency has been embraced in this last model, making for the greatest of ease in opertion and requiring no degree of ability on the operator's part. It will effect an attractive saving in the laboratory and its time saving feature should make additional appeal to the studios along with its more uniform density product. Following are some of the features of the device: No waste of film in making preliminary test. Saves that time necessary to develop, dry and read these tests. Makes the negatives available for printing hours sooner than present system permits. Eliminates guess work and faulty judgment. Will furnish an absolute standard and enable the "lab" to adhere to that standard. Can indicate accurately how this standand may be modified to suit the tastes of discriminating cameramen, where more softness or contrast is desired. Will time a sound track (especially the variable density type) very accurately and furnish a means of checking the development "gamma" upon which good recording so much depends which is impossible to do at present . In night shots and special effects if such scenes are properly exposed the machine will give a proportionae density of printIn scenes on exteriors having a broad area of sky the machine provides for a selection of that portion of the picture most desired, such as close ups and the desired areas of the long shots. Running shots where there is a change of exposure from one point to another or a change of speed the device will indicate every variation and the proper portion selected for printing, obviating the errors that frequently occur, in the present system, when the wrong part is chosen for testing. Where a title is a single word surrounded by a large area of almost clear celluloid, the test track is provided with a compensating screen that brings such titles within the proper printing range. The calibration can be independently set for softer or harder prints, both the denser or thinner negatives receiving the increase or decrease of light in the proper ratio, an improvement over the present system where the printing lights are merely added or subtracted by a number of points dictated by judgment; the error being, by the old method, that the dense negatives may not receive enough additional light and the thin ones too much. The Densometer is equipped with a quick change-over lever from the picture aperture to the sound track or vice versa. It is fitted as referred to before in this article with every control and adjustment for simple and easy handling which enables the operator to maintain all the con ditions, check them frequently and secure an absolute standard at all times.

The construction of these machines, by the most exacting specifications, is being done by the Barsam & Tollar Mechanical Works, 7239 Santa Monica boulevard. • o HUGHES OWNS CAFE Bill Hughes, of Local 37, has branched out with a neat little restaurant at 6208 Lankershim Boulevard.

Electrical energy is concentrated and intensified at the tips of National Photographic Carbons. A large percentage of power is utilized in these carbons to produce strong, penetrating light. Heat waste is minimized. Power costs reduced. Concentration prevents heat from diffusing rapidly into the surrounding atmosphere. This means that National Photographic Carbons burn cooler because they transform electrical energy into light with a minimum development of heat. That's why these carbons give more light per watt! Check up any production that's being shot. You'll find National Photographic Carbons are using less current per candle-power than any other form of studio lighting. If you want pure sunlight put National White Flame Photographic Carbons (hard-arc) in your lamps . . . unbeatable for spots, long shots, or night work. For color photography or close-ups where soft light is required use National Panchromatic Carbons (soft-arc). They're rich in red, orange and yellow-green rays. Remember that all National Photographic Carbons give more light . . . they guard your expense account like a new supervisor on his first job! National Carbon Company, Inc. Carbon Sales Division.
