The Rogue Gels Universal Lighting Filter Kit (Set of 20) simplifies balancing camera strobe output to match ambient lighting conditions and can add dramatic color to images for artistic effect. The Rogue Flash Gel kit uses a tabbed silicone band to quickly attach Rogue Flash Gels to any standard size speed light or shoe mount flash, eliminating the need for expensive or bulky gel holders or sticky hook-and-loop touch fasteners to attach the gels. Simply place one of the Rogue Gel Bands around the flash head, then slip the ends of the Rogue Flash Gel under the band.
