"Many types of light have frequencies too high or too low for the human eye to detect. [...] A number of specialized photography techniques have been devised to work with different light frequencies to make the invisible visible." (Delton T. Horn) | |||
One of those techniques is known as "Kirlian photography". In a Kirlian photograph, subjects are surrounded by colorful auras, which indicate their inner state on a physical, mental, and spiritual level. Professionals or institutions will be asked to read the aura around the person on the picture. | |||
