Ultraviolet induced fluorescence photography

Jump to navigation Jump to search


A photographic technique based on visible fluorescence of an object induced by Ultraviolet radiation. A glass filter used on the lens must absorb all ultraviolet radiation and permit only the visible radiation to pass. Ultraviolet induced visible fluorescence photography must take place in a darkened room, preferably with a black background. One must take care that many recent light-colored fabrics also fluoresce under UV. Any camera or lens may be used because only visible wavelengths are being recorded. Ultraviolet induced fluorescence photography permits to make visible recent varnishes or restoration paint layers producing different photographic signatures from the original ones. Classical uses concern examination of easel paintings, wooden or stone polychrome statues.
