Inon “Clear Photo System” received U.S. Patent No. 6,704,500 on March 9, 2004.
“Clear Photo System” is a method of transmitting a flash signal from a digital camera’s internal strobe to an external strobe via a fiber optic cable. By attaching a piece of “Clear Photo Film” to the digital camera’s internal flash, the visible light portion of the strobe’s flash is cut, so only the non-visible light wavelengths, passing though the fiber optic, are used to trigger the external strobe’s flash. The benefits are elimination of backscatter and image ghosting from camera’s internal strobe flash.
Also, “Clear Photo Film” is now available separately, so users of other strobe systems can take advantage of Clear Photo System benefits. Previously, the film was only bundled with Inon fiber optic kits.

Comment(s):So they have patented unexposed but developed slide film? Because that is basicly what that little strip is that is covering the built in flash that the link shows. I wonder how much that piece of slide film is going to sell for?
For those that don’t know, if you take slide film and have it developed with out the film ever being exposed to light, it will allow Infrared light to pass through. Just tape a piece of this film over your built in flash and the IR will pass through and trip your optical slave flashes. Cost is about $12 for film and development. Or hunt for some scrap leads from your local photo developer. Has to be slide film though, as negatives do not work at ranges behond a foot or so.
