Color photography of infrared ray was applied in the testing of material evidences in the research. We found the images of this technique can demonstrate clearly some important, fine details in original testing material evidence which are imperceptible by eyes. The simple, rapid and accurate attributes make this technique more applicable in the testing of material evidences.
