Question
The exposure index EI for a 35 millimeter camera is a measurement of the amount of light that hits the film. It is determined
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 equation EI = log(). where f is the "f-stop" setting on the camera, and t is the exposure time in seconds. a. Suppose the f-stop setting is 8 and the desired exposure time is 4 seconds. What will the resulting exposure index be? The resulting exposure index will be EI b. Suppose the light meter on a camera indicates an EI of -4, and the desired exposure time is 16 seconds. What should the f-stop setting be? The f-stop setting should be
