Gel system matches outgoing light to ambient room light or enhances black & white image contrast. Chrome Dome increases flash output without sacrificing the softening qualities of the diffusion material. Amber Dome warms the light from your electronic flash for balancing color at dusk or early morning in interiors with tungsten lighting at sunset or for warming your subject in open shade. Mounted on camera the Power Snoot serves as a tool for creating cutting edge special effects. A softer yet dramatic light can be achieved by using the enclosed inverted white dome.
