Light Measurement for Exposure Control
This paper defines the various factors that arc involved in photographic exposure control. The relationships of these factors arc developed under special and general conditions. The importance of the key-light intensity and relative location of source is shown. A formula for determination of setting of camera exposure controls is developed. Practical application of the fundamentals to the design of photographic exposure meters is discussed.
