Exposure Meter for High-Speed Photography
E. T. Higgons · Journal of the Society of Motion Picture Engineers · 1949
This paper reviews the problems involved in the process of evaluating high-intensity illumination levels and the establishment of proper exposure criteria for high-speed motion picture cameras. The problems involved in the design of a suitable light-measuring instrument are discussed, concluding with a detailed description of a light meter which has recently been developed specifically for the purpose of determining proper camera settings for high-speed motion picture studies under any lighting conditions from normal daylight to illumination values as high as 300,000 foot-candles.
