Abstract
An exposure meter by light equalization, which has as an essential basis the comparative search of the luminous intensity that the view itself captures, in a frosted plate, of the ambient light at the moment of calculation, with the same luminous intensity of another half plate adjacent to it. the previous one, which is equipped with phosphorescence susceptible to previous loading, so that it can be reached by trial and error to equalize both intensities, as the end of the measurement, which will appear translated in the correspondence of the existing graduations in the fixed and mobile elements of the conduit Fixed ocular in which the exposure meter is established.
