ABSTRACT:
A system disclosed is for calculating a light information value, such as an f/stop number, which is determined by a number of light sources such as strobes. The system calculates an optimum f/stop number for each of the strobes as the strobes are fired one after another and, at the same time, calculates after each firing of the strobe an optimum f/stop number for the strobes which have been fired. The optimum f/stop number for the plurality of strobes fired at the same time is displayed.
