Foot Candle definition
Foot candle refers to the measurement of light. The term originated from exactly what its title is; the light of one candle that is one foot away is one foot candle. Light meters convert foot candle numbers into an f-stop measurement. However, one should realize that there exists several kind of film speeds. Thus, using foot candles as a reference point is not necessary recommended because f-stops may not correspond exactly to any given number of foot candles since there are so many film speeds.
