Abstract

System and method for rapid measurement of an exposure light source and calculation of filter selection for proper color balanced exposure of a light sensitive medium includes measurement of the light source with a spectroradiometer and calculation of color log exposure differences for successive filters taken from a database list with the filter selection being based on a minimum overall difference value derived from the summation of the absolute values of the individual color log exposure differences.
