Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges. It is named after Soviet inventor and researcher of Armenian descent Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate. The technique has been variously known as electrography, electrophotography, corona(l) discharge photography (CDP), bioelectrography, gas discharge visualization (GDV), electrophotonic imaging (EPI), and, in Russian literature, Kirlianography. Kirlian photography has been the subject of scientific research, parapsychology research, and art. Paranormal claims have been made about Kirlian photography, but these claims are rejected by the scientific community. To a large extent, it has been used in alternative medicine research.
History In 1889, Czech Bartoloměj Navrátil coined the word "electrography". Seven years later in 1896, a French experimenter, Hippolyte Baraduc, created electrographs of hands and leaves. In 1898, Polish-Belarusian engineer Jakub Jodko-Narkiewicz demonstrated electrography at the fifth exhibition of the Russian Technical Society.
In 1939, two Czechs, S. Pratt and J. Schlemmer, published photographs showing a glow around leaves. The same year, Soviet electrical engineer Semyon Kirlian and his wife Valentina developed Kirlian photography after observing a patient in Krasnodar Hospital who was receiving medical treatment from a high-frequency electrical generator. They had noticed that when the electrodes were brought near the patient's skin, there was a glow similar to that of a neon discharge tube. The Kirlians conducted experiments in which photographic film was placed on top of a conducting plate, and another conductor was attached to a hand, a leaf or other plant material. The conductors were energized by a high-frequency high-voltage power source, producing photographic images typically showing a silhouette of the object surrounded by an aura of light. In 1958, the Kirlians reported the results of their experiments for the first time. Their work was virtually unknown until 1970, when two Americans, Lynn Schroeder and Sheila Ostrander, published a book, Psychic Discoveries Behind the Iron Curtain. High-voltage electrophotography soon became known to the general public as Kirlian photography. Although little interest was generated among western scientists, Russians held a conference on the subject in 1972 at Kazakh State University. Kirlian photography was used in the former Eastern Bloc in the 1970s. The corona discharge glow at the surface of an object subjected to a high-voltage electrical field was referred to as a "Kirlian aura" in Russia and Eastern Europe. In 1975, soviet scientist Victor Adamenko wrote a dissertation titled Research of the structure of High-frequency electric discharge (Kirlian effect) images. Scientific study of what the researchers called the Kirlian effect was conducted by Victor Inyushin at Kazakh State University. Early in the 1970s, Thelma Moss and Kendall Johnson at the Center for Health Sciences at UCLA conducted extensive research into Kirlian photography. Moss led an independent and unsupported parapsychology laboratory that was shut down by the university in 1979.
Overview
Kirlian photography is a technique for creating contact print photographs using high voltage. The process entails placing sheet photographic film on top of a metal discharge plate. The object to be photographed is then placed directly on top of the film. High voltage current is momentarily applied to the object, thus creating an exposure. The corona discharge between the object and the plate due to high-voltage is captured by the film. The developed film results in a Kirlian photograph of the object. Color photographic film is calibrated to produce faithful colors when exposed to normal light. Corona discharges can interact with minute variations in the different layers of dye used in the film, resulting in a wide variety of colors depending on the local intensity of the discharge. Film and digital imaging techniques also record light produced by photons emitted during corona discharge (see Mechanism of corona discharge). Photographs of inanimate objects such as coins, keys and leaves can be made more effectively by grounding the object to the earth, a cold water pipe or to the opposite side (polarity) of the high-voltage source. Grounding the object creates a stronger corona discharge. Kirlian photography does not require the use of a camera or a lens because it is a contact print process. It is possible to use a transparent electrode in place of the high-voltage discharge plate, for capturing the resulting corona discharge with a standard photo or video camera. Visual artists such as Robert Buelteman, Ted Hiebert, and Dick Lane have used Kirlian photography to produce artistic images of a variety of subjects.
Research Kirlian photography has been a subject of scientific research, parapsychology research and pseudoscientific claims.
Scientific research Results of scientific experiments published in 1976 involving Kirlian photography of living tissue (human finger tips) showed that most of the variations in corona discharge streamer length, density, curvature, and color can be accounted for by the moisture content on the surface of and within the living tissue.
Konstantin Korotkov developed a technique similar to Kirlian photography called "gas discharge visualization" (GDV). Korotkov's GDV camera system consists of hardware and software to directly record, process and interpret GDV images with a computer. Korotkov promotes the device and research in a medical context. Izabela Ciesielska at the Institute of Architecture of Textiles in Poland used Korotkov's GDV camera to evaluate the effects of human contact with various textiles on biological factors such as heart rate and blood pressure, as well as corona discharge images. The experiments captured corona discharge images of subjects' fingertips while the subjects wore sleeves of various natural and synthetic materials on their forearms. The results failed to establish a relationship between human contact with the textiles and the corona discharge images and were considered inconclusive.
