Kirlian photography?

I was reading this article and they mentioned a Kirlian photograph in it. I had never heard of Kirlian photography before so I googled around and found some info. Basically its a special technique used to get a camera to capture the invisible energy field or aura that all living things supposedly give off.

This is a Kirlian photo I found on google:

Wikipedia has a good description of what it is here

Here is a skeptical description of it which I tend to side with as I am pretty skeptical about this kirlian photography.

This explanation makes the most sense to me as I personally think its BS.

"Living things...are moist. When the electricity enters the living object, it produces an area of gas ionization around the photographed object, assuming moisture is present on the object. This moisture is transferred from the subject to the emulsion surface of the photographic film and causes an alternation of the electric charge pattern on the film. If a photograph is taken in a vacuum, where no ionized gas is present, no Kirlian image appears. If the Kirlian image were due to some paranormal fundamental living energy field, it should not disappear in a simple vacuum "


Anyway I would like to know what fchatters think of it? Is it really an energy field or just BS?
