The GAM MV-INCD CineFilter Color Correction Filter (20 x 24" Sheet) is a roll of color correction medium used to convert multi-vapor lamps to tungsten. It converts 7160K to 3200K, 3200K to 2060K, 5600K to 2840K, and 155000K to 5600K. The light loss with this gel is 1.5 stops, with 53% transmission. The color of the gel is clear and clean, with excellent transmission characteristics, and it won't scratch off the surface of the medium. The clear polyester base is optically clear and doesn't tear, puncture, crack or deteriorate at high temperatures. Because the multi-vapor lamp's interrupted spectrum changes during its life cycle, the correction is not 100% accurate. Supplied in a 20 x 24" (50 x 60 cm) sheet.
