COLOR BALANCE OF COLOR-IR FILM

A SEMI-QUANTITIVE METHOD IS DESCRIBED FOR THE SELECTION OF A SUITABLE COMBINATION OF KODAK WRATTEN OR COLOR COMPENSATING FILTERS AND THE EXPOSURE FACTOR REQUIRED FOR OPTIMUM COLOR BALANCE IN COLOR-INFRARED FILM. THIS METHOD DOES NOT REQUIRE SOPHISTICATED PHOTOGRAPHIC TECHNIQUES OR EQUIPMENT, THE ONLY PREREQUISITE BEING CONSISTENT PROCESSING CONDITIONS AND A REASONABLE STOCK OF FILM WITH SIMILAR CHARACTERISTICS. TABLES ARE PRESENTED TO FACILITATE THE ESTIMATION OF THE COLOR BALANCE AND EXPOSURE FACTORS OF FILTER COMBINATIONS.
