July 1947 PHOTOGRAPHING THINGS TO COME 85
until research pointed out that the fault lay not with the aircraft or radar, but with radar interpretation, that real progress was made. You have seen radar maps of cities, coastlines, etc., and probably have wondered how anyone could make sense out of the things — let alone distinguish an island from a battleship. Imagine what it was like when there were no maps !
The 0-5 A camera did not just grow. Many trials had to be made and some errors committed before it first saw the light of radar. However, from the first radar recording camera, which appeared in 1942 (a Kodak 35 with a total of 36 exposures), to the present model, much progress has been made. Today's 35-mm 0-5.4, the joint result of research by the Army, Navy, and MIT, has a 100-ft film magazine which can be replaced in 15 sec, giving thereby an almost unlimited number of exposures. No longer does the operator have to choose which of a few sweeps he can record. A simple push button permits him to set the camera for every sweep, every other sweep, every tenth, or every sixtieth sweep. No longer does the radar operator have to focus the main scope and then focus the auxiliary scope used for the camera. An elbow beam splitter with a color-selective coated surface permits the same scope to be used by operator and camera. Throughout the development of the radar recording camera, we have consistently reduced its size and weight. The 0-5 A model with all its accessories weighs only 25 Ib and requires only 5/8 cu ft of space.
Despite this progress, tomorrow's radar recording camera will have to be smaller and lighter, have an even larger film capacity, and be adapted to remote control — perhaps from miles away. It will be used to chart the route for tomorrow's navigation, and provide the road maps for three-dimensional color photography
Among general utility motion picture cameras, my nomination for the future is the A-6 model. Because AAF motion picture cameras in operation throughout the war did not satisfactorily fulfill all aerial requirements, the A-6 Model finally was designed. It is a 35mm camera with operating speeds of 16, 24, 32, and 48 frames per sec and has an 87rdeg shutter which permits Vioo of a second exposure when operating at the rate of 24 frames per sec.
Unlike many of the earlier models which were modifications of existing ground cameras, the A-6 was built primarily for aerial use. As a consequence, special features were required. Among these are a 3-lens turret, which prevents vignetting with lenses between 25 mm
