Color correction gels are used to improve overall color balance in an image by adjusting the color temperature of the flash to better match other ambient light sources. White balance your camera and color balance your speedlights for consistent and uniform color in mixed lighting environments.
The Correction Filter Kit includes 3x each of the following color correction gels: 1/4 CTO, 1/2 CTO, Full CTO, 1/2 CTB, Plus Green, Full White Diffusion (1 Stop).
Identify your light source, select the appropriate color correction gel(s), then attach the gel(s) to your flash. It is important to then set a custom white balance, or set the camera to the same white a lance setting as shown on the attached correction gel.
CTB gels are used to color balance flash to shade, or blue sky ambient light sources.
CTO gels are used to color balance flash to incandescent, tungsten, or halogen ambient light sources.
Plus Green gels are used in combination with CTO gels to color balance flash to fluorescent ambient light sources.
With a coverage area of 3" x 2.5" (76mm x 63mm) Rogue Flash Gels are large enough to cover even the largest flash heads, and they can be creased or trimmed for smaller flash heads as desired.
