Today: – Foot Candle - Measurement of light. One foot candle is the light of one candle, one foot away. Many light meters will use foot candles as a starting number, which then must be converted into an f-stop based on the sensitivity of the film you are using. (Because of the great variety of different film speeds it is sometimes ambiguous to talk too much about foot candles, since a given number of foot candles will not yield the same f-stop from one film speed to another.)
