Abstract: A photographic color effects lighting filter system made up of a series of lighting filters which are designed to be placed in front of one or more lighting sources. The lighting color effects filter series is made up of groups of filters wherein each of the filter groups is composed of a plurality of filters wherein each filter within a given group provides selective absorption of light having a color corresponding to one of the primary, secondary or intermediary colors. Each of the filters within a given group has a specific effective absorption density. The effective absorption densities are calibrated so that the selected absorption densities are the same for each of the different color groups.
