Rosco Cinelux #364 Blue Bell Filter, 48"x25' Roll

The Rosco Cinelux #364 Blue Bell Filter (48"x25' Roll) is manufactured with a unique technology to insure the longest possible life under hot theatrical lights. Three discrete layers are combined in a tri-extrusion process. By sealing the colored layer between two microscopically thin layers of clear film, dye migration is minimized and effective life is extended.
