This was taken with a Fuji camera designed mainly for forensic photography. It doesn't have an Infrared filter over the sensor like most digital cameras, so it records both visible light and into the infrared spectrum. By placing an R72 filter over the lens, most of the "visible" light was filtered out and this image was captured using only the reflected infrared light. It was then desaturated in Photoshop and a Topaz filter was applied to achieve the final effect.
