The international photographer (Jan-Dec 1939)

PHOTOGRAPHER ■3a&as«^ January, 1939 — 1 ^Oo0^;cre'^f^ TfiflDEuiimrs ;i" New Photrix SS Exposure Meter with Wider Reach of Sensitivity; Simple Operation The newly announced Photrix SS exposure meter is claimed to fill the gap between indoor and outdoor light control through providing so much additional sensitivity that its measuring range extends from brightest sunlight far into the field of indoor photography. In addition, the Photrix SS boasts of a simple, self-explanatory reading method, of smooth, compact and attractvie appearance and of highest grade accuracy and workmanship. Its movement is made by the Cleveland, Ohio, firm of Hickok for many years a well known name in the field of precision electrical measuring instruments. The design and reading method of the Photrix SS embodies a number of novel and interesting features. While the exposure meter is in the aiming position, it is not ncessary to take any readings of figures at all but only to set the ring so that the red index registers with the needle indication. This automatically lines up all usable combinations of film speed and exposure time on the lower part of the dial. The glass window is provided with a red index and turns in the calculator ring, therebyserving the double purpose of protecting all the scales and of setting the exposure meter for the particular film speed so that the user does not need to remember his film speed every time he takes a reading. The Photrix SS is very flat, measuring only y8"incrl 'n thickness. The surface of the meter is completely smooth without any protruding parts, levers or screws. All figures are under glass, very legible and well spaced. The scales are clearly marked and easy to identify. The casing consists of a one-piece bakelite molding of high strength and rigidity. The movement is operated by a cobalt steel magnet and a high output photocell of permanent stability. The Photrix SS is distributed by Intercontinental Marketing Corp. of New York City. Retail price is $17.50. Improved Slifle Projector Model DP Argus Announced by International Research New brilliance in a slide projector is claimed by International Research Corporation for its Argus Model DP, which will sell between $20 and $25 and will employ a standard 110-120 volt, 100-watt projection lamp in conjunction with a newly engineered condensing and objective lens system. The lamp socket will handle a 200-watt lamp, if desired. Lens focal length is five inches. Streamlined design of the DP projector allows for a generous-sized lamp-house with new ventilation principles that keeps heat to a minimum. It has a die-cast base and all-metal construction, is finished in Argus gray with chromium and Chinese-red trim. Lamp-house is hinged for easy access to lamp, reflector and condensing lenses. An improved type of slide carrier, of heavy-gauge stamped steel with cadmium plated surface, is unusually rigid and holds two two-inch slides securely and without danger of jamming in the slide aperture. There is a tripod socket in the base of the projector, making it unnecessary to rest it on a table or other surface. A locking tilting-foot for elevating the image on the screen is built into the front of the base. The DP is equipped with a nine-foot extension cord, with moulded rubber plug, and a snapswitch on the cord a few inches from the projector. The cord is Underwriters-approved. A carrying case accommodating the projector and 150 indexed slides in a hinged lower compartment will list at around $5.00. When projector and case are ordered together, there will be a list price saving of $1.00 or more. Case is of strong plywood construction, leatherette covered and nickel trimmed. Ampro Brings Out Two Moderately Priced Models of 16 mm Sound-Film Projectors Ampro Corporation is bringing out two new and improved low-priced 16 mm sound-on-film projectors, which are basically new in design, and priced to fit a moderate budget.
