Rosco Roscolux Blue Bell, 20x24" Color Effects Lighting Filter

Because capturing the perfect shot requires precise control over lighting, the Roscolux Blue Bell, 20x24" Color Effects Lighting Filter is an essential tool for photographers and videographers. This vibrant filter produces a stunning blue color effect, ideal for creating naturalistic daylight fill color or a cool area light. With a light transmission rate of 32%, it allows for intense, dazzling, and radiant images.

Crafted by Rosco, a leading name in the film and television industry, this filter is part of their premier Roscolux range. Known globally as "Supergel," Roscolux is the most widely used filter range in the world, thanks to its unique manufacturing process. Unlike ordinary color filters that are surface-coated, Roscolux filters are created through a tri-extrusion process. This involves sealing the colored layer between two microscopically thin layers of clear film, minimizing dye migration and extending the filter's effective life.

More than 65% of the Roscolux line, including this Blue Bell filter, is made from co-extruded polycarbonate plastic, while the remainder is deep dyed polyester. This composition ensures that the filter's color won't easily fade or scratch from heat and physical abrasion, unlike traditional filters where the color is merely painted onto the surface.

The Roscolux Blue Bell filter is available in sheets of 20in. X 24in. (50cm x 61cm) or rolls of 24in. X 25ft. (61cm x 7.62m). For larger dimensions, consider the Cinelux line of filters, available in rolls of 48in. X 25ft. (122cm x 7.62m). Whether you're shooting digital, film, or video, this filter is designed to enhance your creative vision and bring your photographic and videographic projects to life.
