Kirlian Photography |
Kirlian photography refers to a form of photogram made with high voltage. It is named after Semyon Kirlian who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a source of high voltage, small corona discharges (created by the strong electric field at the edges of the object) create an image on the photographic plate.
Kirlian's work, from 1939 onward, involved an independent rediscovery of a phenomenon and technique variously called "electrography," "electrophotography," and "corona discharge photography." The underlying physics (which make xerographic copying possible) was explored as early as 1777 by Georg Christoph Lichtenberg (see Lichtenberg figures). Later workers in the field included Nikola Tesla; various other individuals explored the effect in the later 19th and early 20th centuries. Yet Kirlian took the development of the effect further than any of his predecessors. In controversial metaphysical contexts, Kirlian photography, Kirlian energy, and so on, are sometimes referred to as just "Kirlian." Kirlian made controversial claims that his method showed proof of supernatural auras, said to resemble a rough outline of the object like a colorful halo. An experiment advanced as evidence of energy fields generated by living entities involves taking Kirlian contact photographs of a picked leaf at set periods, its gradual withering being said to correspond with a decline in the strength of the aura. Scientifically, it is considered more likely that as the leaf loses moisture it becomes less electrically conductive, causing a gradual weakening of the electrical field at the drier edges of the leaf.
Kirlian proposed and promoted the idea that the resulting images of living objects were physical proof of the life force, or aura, which allegedly surrounds all living beings. This claim was said to be supported in experiments by the proponents of the paranormal explanation that involved cutting part of a leaf off —the Kirlian images of such leaves, it was said, still showed the leaves as whole, as though the cutting had never happened.

Kirlian Today...
Kirlian photography is used in contemporary research and artistic design. One company who has furthered the reach of Kirlian photography is FullSpectrum. Under the leadership of Nigel Hutchings, FullSpectrum has been working with Kirlian electro-photography since 1978, and has developed digitally enabled technology which is used today in universities, design studios, and health centers worldwide. |
