Tungsten Conversion Filters Tungsten Conversion Filters are a range of blue filters that raise color temperature as needed. Although typically used on tungsten-halogen sources to balance with daylight, the range offers a multitude of technical and aesthetic color correction possibilities. Daylight Conversion Filters AMBER Rosco Sun Daylight Conversion Filters are a range of amber filters that lower color temperature as needed. Although typically used on daylight 5500°K sources to balance with tungsten, the range offers a multitude of technical and aesthetic color correction possibilities. STRAW RoscoStraw Daylight Conversion Filters are a series of yellowish amber filters that lower color temperature as needed. The series is offered as a yellower version of the traditional CTO series and is calibrated to the same color correction and transmission properties. Sun 85 & Neutral Density Filters These filters are usually applied to windows for color correction and/or light intensity reduction. RoscoSun 85 is an amber filter that lowers the color temperature of daylight to balance with 3200°K sources. Rosco Neutral Density Filters reduce the level of exterior light and bring it within the exposure range of interior light levels. Two additional RoscoSun materials combine Sun 85 conversion with Neutral Density reduction. Filters for Controlling Carbon ARC & HMI Lighting A traditional range of filters is also available for Carbon Arc and HMI correction. These filters are all designed to reduce color temperature in discrete steps. Fluorescent Light Filters Standard U.S. Cool White fluorescent bulbs offer a good approximation of daylight except for their distinct green cast. When Cool White fluorescents are encountered in film or video, two color correction techniques are available: either balance all other sources to the fluorescents, or balance the fluorescents to the reference source.
