Aura cameras can be found at every psychic fair. They are fun and exciting, and almost everyone who has gone to a psychic fair has had a chance to sample the results of an aura camera. However, aura cameras are not actually taking a picture of your aura, especially since it is not made of physical light. The name "aura camera" is a bit misleading. It records something else entirely.

How an aura camera works is described at http://www.geocities.com/athens/parthenon/6670/doc/t_auras.html. Sensors are put on your fingers, or are embedded in a chair, and they take readings of electrical resistances in the skin. This is called the galvanic skin response. It varies depending on your skin's moisture and salt level. This information is then fed into the camera and a pattern is generated based on the camera designer's offering of what your aura should look like based on your galvanic skin response. The designer has come up with some ideas about specific colors pertaining to different skin response patterns. As you can well see, this is a highly inaccurate way to find out what your aura looks like. A picture produced by an aura camera is not really a photograph, but an electronically created illusion.
