UV induced fluorescence photography Ultraviolet photography

-


fluorescent materials lit uv light. no filter used absorb violet visible light. photo taken daylight film


photography based on visible fluorescence induced uv radiation uses same ultraviolet illumination in reflected uv photography. however, glass barrier filter used on lens must absorb or block ultraviolet , infrared light , must permit visible radiation pass. visible fluorescence produced in suitable subject when shorter, higher energy ultraviolet wavelengths absorbed, lose energy , emitted longer, lower energy visible wavelengths.


uv induced visible fluorescence photography must take place in darkened room, preferably black background. photographer should wear dark-colored clothes better results. (many light-colored fabrics fluoresce under uv.) camera or lens may used because visible wavelengths being recorded.


uv can induce infrared fluorescence , uv fluorescence depending on subject. uv induced non-visible fluorescence photography, camera must modified in order capture uv or ir images, , uv or ir capable lenses must used.


filters added uv illumination source narrow illuminant waveband. filter called exciter filter, , allows radiation pass needed induce particular fluorescence. before, barrier filter must placed in front of camera lens exclude undesired wavelengths.
