An electrophotography discharge image of a ginko leaf (Ginkgo biloba). Also called Kirlian Photography, this technique shows the electrical discharge around an object. The principle of electrography is based on the corona discharge phenomenon that takes place when an electrically grounded object generates an electrical field, discharging sparks between itself and an electrode.
