Response to EV values on a light meter

Sometimes asking a question is enough to find the answer.

f (stops) icrease in stops, The same is true of EV values. THe film speed increases linearly as does the recipricol of the time (shutter speed) (e.g. 500 for 1/500th of a second)

With the above, the relation is (or seems to be)

(f^2)*T=ISO*EV^2

where f f stop T 1/time (100 for 1/100th) ISO film speed EV Exposure value
