Infrared photography is nothing new and in the reflected infrared mode its property of seeing thorough certain materials is well known. However a a seldom seen and used application allows the trained investigator to visualize information that has been washed out of documents and is undetectable to the unaided eye. This is facilitated by new infrared sensitive digital cameras such as the Fuji IS-1. Added here in February 2008.
