The corona-like images might be auras or might be something less remarkable. It might just be the result of the combined interactions of the induced voltage, the length of exposure, the humidity of the air, and the moisture and resistance of the skin of the hands that held on to the sensor’s of the aura cameras.
Checking out the aura camera is indeed tempting but the basic price is prohibitive. One basic set of the aura camera, which includes the cables, the sensors, a video, a book, and several rolls of films, is worth around $10,000. A cursory interest in aura photography would not be sufficient motivation to buy an aura camera. There are, however, other cheaper aura cameras which prices range from $2,000 to $5,000.
