Electrophotonic imaging with the GDV camera is one of the emerging technologies in the area of biofield research. Based on the Kirlian effect, a digital image is taken of photon emission patterns around each fingertip. Software then analyzes the sectors of each finger as they relate to reflex zones in organs and structures in the body. Nearly 1000 papers have been published (mostly in Russian) on GDV research and a few hundred more in the West. A recent review of GDV research applied to medicine and psychology can be found in the book Electrophotonic Applications in Medicine: GDV Bioelectrography.
