Cinefilters 1535 Eighth Blue CTB Color Correction Filter

Use GAM 1535 1/8 Color Temperature Blue to correct tungsten lamps toward daylight. Eighth Blue CTB absorbs warmer colors to balance color temperature between varying light sources. 

Lighting Directors call for G1535 Eighth CTB filters to light sunlit interiors, and to achieve cooler color temperatures from warm incandescent and halogen lighting fixtures. Motion picture crews and studio staff use CTB correction to intermix tungsten halogen sources with HMI fixtures, arc sources, and other daylight color temperature lights.
