How to remove the fresnel lens of a Vivitar 283 flash to convert it into a full spectrum flash suitable for use with ultraviolet photography. The fresnel lens of the flash is very effective at blocking any ultraviolet light output by the xenon flash tube. By removing this lens and replacing it with clear plastic the flash is converted into a full spectrum flash.
To take UV photos you will also need a camera sensitive to UV light, a lens that transmits UV light, and a filter that blocks visible and IR light while passing UV light as well. For more info on UV photography, Klauss Schmitt has a good tutorial on what's involved here: http://photographyoftheinvisibleworld...
