Full description

The Gemetrix Mobile App is for use with the PL-Inspector or Jewellery Inspector. The app allows control of your smartphone camera, using the same settings for both short-wave ultra-violet (SWUV) and long-wave ultra-violet (LWUV) illuminations. The controlled settings are for exposure, ISO, colour temperature and focus. The two images can then be compared either through alternating views or using a slider. Images with SW and LW labelling can be saved to your image gallery. A quick guide to using a PL-Inspector or Jewellery Inspector can be downloaded from our website. Gemetrix not to be confused with gmetrix.
