kirlian photography was developed in russia by the engineer and electrical researcher semyon kirlian, who along with valentina k. kirlian of kazakh state university, ussr, invested their lives researching photographic techniques to demonstrate the electrical discharges that came from living creatures.

they concentrated on recording techniques that showed the luminous telsa discharges in the air surrounding an object which is subjected to a high voltage at a frequency that is too high to be perceived.
after refining the process, kirlian claimed that his corona photographs produced information related to the energy of living things.
when used in humans, the observed kirlian patterns change with the person's mental and physical state and have been used as a qualitative indicator of the efficiency of a particular course of therapy and for certain diagnostic purposes . it is interesting that the acupuncture points of the body can be observed in this way. kirlian photographs of the blood and tissue samples have also been used for diagnostic purposes.
when organically grown fruit and vegetables are photographed in this manner, they show a corona almost 40% larger than regularly grown produce.
