American cinematographer (Jan-Dec 1941)

mounting their flashguns on cameras like the Rolleiflex, Leica and similar miniatures. Get one of these brackets. You'll see it has at least two holes on each arm, threaded to accept the regular ^-inch tripod-screw, and a bolt which can be fitted into any of the holes, threaded so it screws into the camera's tripod socket. Screw this into one of the holes on the bottom of the L, and attach the bracket to the camera with it so that the upright part of the L comes up at one side or the other of the camera. Then use the other to screw the bracket onto the tripod. You can use the upright part of the bracket to hold a clamp-on photoflood lamp beside and slightly above the camera, or you can use a ^-inch bolt to mount a "Dinky Inky" on the bracket. This will give you a lighting unit — ■ floodlight or spotlight — beside the camera for front-lighting close shots of people, and which pans and tilts as you pan and tilt the camera to follow them. ALBERT CHRISTIANSON Showcase (Continued from Page 439) ring which the company has always used in its cine projectors to assure positioning the lamp for maximum illumination. The top of the Slide-master lamphouse is a hinged snap-cover, which automatically breaks the electrical circuit as it is opened, so that lamps may always be interchanged with perfect safety. It is further stated that since the globe burns base up, gloves are not needed to remove a hot lamp. The Filmo Slide-master is designed to take 500-, 750-, or 1000-Watt base-up lamps, providing whatever degree of illumination is required, at the maximum giving considerably greater lamp-power than is common among minislide projectors. It is stated that the lamphouse is so designed that there is no lightspill from this projector; the darkened room stays dark, except for the brilliant picture on the screen. With such high-powered lamps operating in a comparatively small lamphouse, forced cooling is an obvious necessity. In this installation the powerful, motordriven ventilating-fan automatically alters its speed according to the wattage of the lamp being used. Thus when a 1000-Watt lamp replaces one of the smaller globes, the motor automatically increases its speed, and therefore the blast of cool air, and decreases speed when a smaller lamp is used. The forced cooling draft circulates throughout the projector, with special attention given to cooling the slide itself. Motor and fan-bearings are sealed in, lubricated for life. The condenser includes two heat-absorbing glass filters, for maximum slide protection. Two clearly-marked switches are provided, one controlling the complete projector-circuit, the other operating only the lamp. The lamp cannot be turned on unless the motor fan is running. The Filmo Slide-master projector is offered with a choice of 3 V2-, 5-, or 7%inch /:4.5 lenses, all of which are stated to be anastigmatic and interchangeable mounts. Focusing is by a rack-andpinion assembly, and lenses may be locked in focus. Self-locking tilt-controls, one at each end of the projector, provide either up or down tilt through a wide range. The slide-carrier, of the conventional horizontal-shift two-slide type, is of diecast metal with special air-passages to provide circulation of cool air around the slide. Slides are held in the focal plane by springs.

It is stated that it is important that Kotavachrome prints should not be exposed for long to direct sunlight. Kotavachrome Professional Prints will be available through dealers in September, according to the Eastman organization. Booklet on DuPont Copying Films A new 20-page booklet entitled "DuPont Films for Documentary Reproduction" should prove of interest to both the hobbyist and commercial user of film for photographic copying. All necessary information such as speed ratings, exposure guides, spectrograms, developing times and storage recommendations are included for DuPont Safety Microcopy, the firm's ultra finegrained panchromatic negative with an effective resolving-power of more than 193 lines per millimeter and for DuPont Safety Positive and Fine Grain Safety Positive, companion films for use in documentary reproduction. Copies may be obtained by addressing the DuPont Film Mfg. Corp.. 9 Rockefeller Plaza, New York, N. Y. New Bolex Frame Counter A useful accessory for Bolex cameras is the recently-announced frame-counter, which attaches to the motor-crank shaft of the camera and counts individual frames while the camera is in forward or reverse motion and whether being run by spring-motor, electric-motor or hand-cranked. Two dials ai'e provided; one registers each frame as it passes the gate, while the other registers 50 feet at a time and keeps a record up to 1000 frames. All Bolex cameras with serial numbers higher than 9400 provide means for attaching this accessory instantly.
