- Developed by a Russian couple and based on the theories of Rudolf Steiner, Kirlian photography is a diagnostic technique that makes use of a high-voltage, high-frequency electrical field. This electrical field interacts with an object (for example, a part of the human body) that is "photographed." The photographic "plate" may be used to make a diagnosis.
- Kirlian photography can produce a colored image, which is believed by some to reflect a person's aura.
- The safety of Kirlian photography has not been established. Kirlian is not a substitute for established methods of diagnosis. People with pacemakers and implanted cardiac defibrillators should use Kirlian photography with caution, as they may be affected by the electrical field.
