The Rosco Cinegel range includes over 200 tools for controlling light, including color corrections, diffusions, our patented CalColor System, The Storaro Selection and Cinelux. Since it's introduction in 1970, Cinegel has continually developed and grown to meet the working needs of professionals working behind the camera. In 1974, Rosco was honored with an Academy Award for developing the Cinegel range and again in 1998 for the development of the CalColor range of calibrated colors for camera.

All of the filters in the Cinegel range are available in 20"x24" sheets and 48"x25' rolls, unless otherwise noted. The Cinegel range of color correction and color effects filters are manufactured using deep-dyed polyester for heat stability & superior color transmission.
