BeyondVisible
Ultraviolet, Infrared and Luminescence Photography

Shane Elen

NOTE - THIS SITE IS UNDERGOING A LONG OVERDUE UPGRADE WHICH SHOULD BE COMPLETE BY WINTER 2014


The application of film based luminescence, reflected ultraviolet and infrared photography has always been a bit of a tedious task but this has been greatly simplified through digital photography. While there are several interesting sites that discuss UV and IR techniques, this site provides some unique contributions to the field in application, equipment data and modifications. Included is a unique gemological forensic application, presenting the first ever reported and published images of pearls using reflected-ultraviolet photography (2006 Gem Research Conference). Future additions to the site will also include some artistic as well as scientific application.

Background
Since 1978 I have specialized in solid-state materials characterization through the application of microscopy and spectrometry. This involved working with some unique materials, advanced imaging and spectrometry techniques, some of which will be presented on this site (soon). Since the majority of my work has involved characterizing material features beyond visible perception, beyondvisible.com seemed an appropriate domain name.

    Natural color gems and their treated color counterparts often exhibit a similar reflectance in the visible region of the spectrum, but may show a distinct difference in the ultraviolet or infrared region. Reflected UV and IR photographic techniques exploit these differences. The observation of fluorescence color or zoning is also often important in identifying natural and synthetic gemstones, as well as color treatments. This poster presentation demonstrates the possible application of these specialized digital photography techniques to identify natural and treated colour pearls, however, they may be applicable to other gem materials.
