Photographers, cinematographers and lighting designers use colored filters or gels in front of lights. Whether they want to create a romantic moonlit setting or a vicious, angry fight, they have the colors they need to achieve the effect. We have created digital equivalents to the lighting gels created by Rosco and these same exact colors can be applied to the entire image or inside a gradient. These four Rosco filters contains gels from the Calcolor, Cinegels, Cinelux and Storaro Selection. For detailed information about Rosco Gels, you can visit their website at www.rosco.com
