The Ray Flash is a unique adapter for your hot-shoe flash unit designed to replicate the lighting effect produced by traditional, expensive, and heavy powered studio ring light units.
The Ray Flash is portable and lightweight, and has been designed to take advantage of a camera’s TTL metering capabilities. Because the Ray Flash relies on the hot-shoe flash to generate its light, it contains no electronics, no flash tubes and requires no cumbersome cables. The light distribution is accomplished through a sophisticated system of internal light-shapers designed to distribute and project the light evenly around the lens.
The Ray Flash creates the distinctive ring light effect: a three-dimensional shadow-wrapped look around the subject. Because ring flash light originates from a circle around the lens, it produces a virtually shadowless look on the front of your subject, while producing a soft even shadow around the edges. The versatile Ray Flash is ideally suited for fashion, wedding, portrait, journalist and macro photography as either a main or fill light.
