Ultraviolet photography Silicon (from which DSLR sensors are made) can respond to wavelengths between 1100-190 nm. Photography based on visible fluorescence induced by UV radiation uses the same ultraviolet illumination as in reflected UV photography. However, the glass barrier filter used on the lens must now absorb or block all ultraviolet and infrared light and must permit only the "visible" radiation to pass. Visible fluorescence is produced in a suitable subject when the shorter, higher energy ultraviolet wavelengths are absorbed, lose some energy and are emitted as longer, lower energy visible wavelengths. UV induced visible fluorescence photography must take place in a
Ultraviolet (Light My Way) Ultraviolet (Light My Way) "Ultraviolet (Light My Way)" is a song by Irish rock band U2 and the tenth track from their 1991 album "Achtung Baby". Ostensibly about love and dependency, the song also lends itself to religious interpretations, with listeners finding allusions to the Book of Job and writers finding spiritual meaning in its invocation of the light spectrum.
