    Abstract: A photometer system of the type having a photoelectric sensor receiving light through selectable different-sized apertures and selectable different density optical filters is provided with electronic circuitry including a numerical read-out means for automatically compensating the photo-sensor output in accordance with selected aperture and filter settings and for providing a direct numerical reading of the measured light. The circuitry automatically calculates the proper scale or multiplier of the direct reading, again in accordance with the selected apertures and filters, and provides a numerical display of such scale multiplier. Additionally, a gain control for changing the sensitivity of the photoelectric sensor is provided with an output indicative of the gain setting. This gain setting information is electronically fed to the computer along with the aperture and filter information for automatically computing and displaying the correct scale or multiplier factor from all of these independent variables.
