2. A method for photographing the etheric aura (electromagnetic field) around plant and animal parts. In 1939 Semyon Kirlian, a Russian scientist, developed Kirlian photography, which reveals an energy discharge around fingers, plant leaves or other living forms. Rather than photographing the actual aura, the Kirlian photograph shows a corona discharge occurring when the subject is placed on a film upon a metal plate charged with high voltage electricity. See: electrophotography.
