In France the Br£guet Company has brought out a new 150-amp automatic carbon-arc lamp for stage lighting which has received considerable notice because of its stability.
While no mercury-cadmium lamps are in present use for set lighting in the West Coast studios, the bulbs are available and are being evaluated by the Research Council.2
Reflector-type incandescent bulbs such as photoflood and photospot lamps have been increasingly used on location where the documentary type of lighting is indicated and for nontheatrical releases.2-12'13'14
Cameras and Accessories. A system for special effect shots has been devised and applied at present to panning and tilting the camera, which permits the cameraman to pan and tilt the camera in a normal manner and follow the action as desired. A record is made of the movement and, for subsequent ex
posures on the same film, the record controls the camera movement, matching the original relation between the camera position and picture frame during these subsequent shots.15
In France two new lenses were announced. "Retrofocus," a very short focus lens designed so as to permit attachment and use on normal 35-mm cameras, and "Erax," a highly corrected lens developed by Socie"te* Kinoptik in which the graduation of the aperture of the diaphragm is proportional.
The Eclair Camerette, introduced in the United States from France in 1949, now has a companion model, the "Cameflex," which takes 35-mm and 16-mm film interchangeably (Fig. I).16-17
The "Aquaflex," shown in Fig. 2, was introduced in the United States in 1950, the first one being used by the United States Navy. Essentially, it is a standard 35-mm Camerette with a specially designed magazine in an underwater blimp which permits external stopping and starting, speed control, focus and diaphragm changes.
