Other measures of illuminance are the lux and EV (exposure value)
L [lx] = 2.5 x 2EV
1 foot-candle = about 10.764 lux;
EV 1 roughly equals to 0.46 foot candle or 5 lux.
Note that EV is a linear progression while foot candle and lux are not. Also note that the below table is hypothetical, the f/stop or aperature will change depending on the film speed.
