What is the Ray Flash?
The Ray Flash (U.S. and international patents pending) 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 cameras 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 Flashis ideally suited for fashion, wedding, portrait, journalist and macro photography as either a main or fill light.
Weighing just 13-14 oz, the Ray Flash is lightweight and is easily supported by hot-shoe mounted flash units. The 4 1/8 internal diameter of the Ray Flash is large enough to accept almost all professional lenses from Nikon & Canon.
The Ray Flash is specifically designed for the Canon 580EX (I & II), Nikon SB800 and Nikon SB900 flash units. However, existing Ray Flash models will also fit older Nikon flash units, including the SB24, SB26 and SB600, as well as selected flash units from Sony, Metz, Olympus, and Sigma.
The Ray Flash does not interfere with a camera's TTL functions. In fact, one of the easiest techniques to use when shooting with the Ray Flash is to set the camera to Manual exposure (to control the ambient light), and to set the flash to TTL.As with standard flash use, manual exposure control may require the use of a light meter or test-shots.
At a distance of 10 feet from a given background you can expect an even distribution of light approximately 8.5 feet wide. This means the Ray Flash can easily handle small group shots at medium distances.
Photographers frequently ask how much light is lost, or consumed by the Ray Flash. The Ray Flash was painstakingly designed to produce a balance between quality of light and power, the result being a design that efficiently transmits approximately 92% of your flash's output. A direct comparison with bare flash is overly complicated because the concentration of light from a bare flash is dramatically affected by the flash's zoom setting, whereas the light pattern of the Ray Flash remains constant.
How to Fit the Ring Flash Adapter
The Ray Flash was designed with convenience in mind. What good is a ring light if it is too cumbersome to use?
The Ray Flash quickly attaches to a camera mounted hot shoe flash by sliding over the head of the flash. Once in place, simply turn the lock screw on top of the Ray Flash to secure it in place. This design allows the Ray Flash to hang suspended from the flash unit, thereby freeing your hands to comfortably hold and operate the camera and lens.
Because the Ray Flash was designed to fit specific camera and flash combinations, no modifications are required to attach the Ray Flash. However, if you are using the Ray Flash with similarly sized flash units from other manufacturers (Sony, Olympus, Metz, etc.), then it may be necessary to use one of the included rubber fitting wedges to get a tight fit.
Please note, the Ray Flash may not mount to a flash that has any materials stuck to it, such as Velcro.
Ray Flash Models
The Ray Flash is specifically designed for the Canon 580EX (I & II), Nikon SB800 and Nikon SB900 flash units. The Nikon SB26, SB28 and SB600 models are also compatible with the Ray Flash.
