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

With the Roscolux Slate Blue, 20x24" Color Effects Lighting Filter, you can effortlessly achieve a clean, medium blue hue, perfect for replicating sky color or moonlight effects in your photography or videography projects. This high-quality filter, with a light transmission rate of 20%, is part of Rosco's premier Roscolux range, renowned globally for its durability and longevity under hot theatrical lights.

Crafted using an innovative tri-extrusion process, the Roscolux Slate Blue filter features three discrete layers. The colored layer is sealed between two microscopically thin layers of clear film, significantly minimizing dye migration and extending the filter's effective life. This unique manufacturing process sets Roscolux apart from ordinary color filters, which are typically made by surface coating clear polyester plastic film.

More than 65% of the Roscolux range, including this Slate Blue filter, is made from co-extruded polycarbonate plastic, while the remainder is made from deep dyed polyester. This composition ensures that the filter's color is not easily removed by heat or physical abrasion, preventing quick fading and scratching that are common with other filters.

The Roscolux Slate Blue filter, also known under the trade name "Supergel" overseas, is currently the most widely used filter range in the world, testament to its professional-grade quality and versatility. It is available in sheets of 20in. X 24in. (50cm x 61cm), making it a suitable choice for a variety of photography and videography needs. For larger dimensions, consider the Cinelux line of filters, available in rolls of 48in. X 25ft. (122cm x 7.62m).
