What is the easiest way of taking Kirlian pictures (photographic techniques used to capture the phenomenon of electrical coronal discharges)?
Kirlian photography, although the study of which can be traced back to the late 1700s, was officially invented in 1939 by Semyon Davidovitch Kirlian. The Kirlian photographic process reveals visible “auras” around the objects photographed. These photographs have been the subject of much myth and controversy over the years.
For clarification, I'm not concerned whether this is a digital or analog solution.
