High‐voltage‐radiation photographs, otherwise known as Kirlian photographs, are normally obtained as contact prints on photographic film or paper. However, the same kind of images can be formed by high‐voltage corona discharges on bulk dielectrics and on thin films of various materials deposited on glass substrates. The transport of thin‐film materials has been observed, accompanied by the formation of droplets in the case of oily films. Moisture released by objects of living and unanimated matter is directly recorded on some thin films.
