The exposure index EI for a 35-millimeter camera is a measurement of the amount of light that hits the film. It is determined by the 2 equation E1 = logz (f7 ), where f is the "f-stop" setting on the camera and t is the exposure time in seconds. Suppose the fstop setting is 2 and the exposure time is 1 seconds. What will the resulting exposure index be? EI= Submit You have used 0 of 3 attempts "' V Save Reset
