Capturing Mystical Energy Fields 00:02:22
Adherents to New Age mythology and all its many branches, such as energy healing, are always keen to find evidence that supports their view that people are mystical beings of energy, not mere flesh and blood.
One discipline which has been trying to prove this for a while is the field of aura photography.
Ways that a camera can be used to capture the actual spiritual energy field around a person.
Well, what does the science have to say about these techniques?

How to see your aura.
Today we're going to set up a special camera and view a mystical energy field surrounding your body that's normally visible only to certain sensitive people.
Our subject today is aura photography.
A listener from Chile wrote in with the following account of a late-night infomercial aired on Chilean television.
There was a guy by the name of Harold Moscovitz giving a show entitled Des Arroyo Lus Dorada, or Golden Light Development.
The Science of Heat Halos 00:03:29
He was claiming to provide all sorts of healing through esoteric ways such as reading one's aura and then providing techniques for resolving problems found within it.
Basically the show was claiming to provide relief for pretty much any ailment and all one has to do is attend a seminar or two, paid of course, in order to learn the mystic ways.
He had numerous people swearing to have been cured of various serious ailments and one woman even held up an x-ray of tumors she had that were now magically cured.
Chile is a fine country but it does have a significant number of people that do not have access to a decent education or health care and this con man is basically telling them he can cure cancer.
Well there's nothing new about psychics claiming to see your aura.
What's missing is any kind of a half-decent explanation for what this aura supposedly consists of.
It's really easy to throw around scientific sounding terms like bioelectromagnetic fields or life energy, but such terms do not have any legitimate meaning.
We have to ask some basic questions.
Does this thing called an aura really exist?
Does it convey any useful information about the person?
How might it be possible that some people can see it or sense it while others cannot?
To answer the first question, do auras actually exist?
We have to abandon untestable verbal claims from psychics who say they can see them but offer no evidence, and look instead to testable evidence, namely aura photography.
There are three types of aura photographs.
The first, which is sometimes seen in video and is usually in color, is simple infrared photography.
To take an infrared photograph with a conventional film camera, simply use infrared-sensitive film.
An infrared photograph shows heat.
A shot of a dead object at room temperature appears black or at the same color as the general background, but a living person or other warm object appears white or in a color video at a warmer temperature.
Charged particles near the skin surface or near the surface of any warmed object are excited by the radiated heat and will appear as a glowing band around the person or object.
Simple heat does not have any of the mystic qualities attributed to auras and can be produced equally dramatically with any dead object if you just warm it up.
The second type of aura photograph is called Curlian imaging.
It's named for Semyon Davidovich Kurlian, the Armenian electrician who discovered it in 1937, though it didn't really become popular in the world of aura enthusiasts until the 1970s.
Curlian's images of auras are all black except for the aura itself, which is manifested as a thin band of jagged white surrounding an object.
To take a Curlian image, the subject to be photographed is placed on a photographic plate, which is electrically isolated above an aluminum electrode.
Another electrode is connected to the subject, and the resulting image is thus burned onto the photographic plate.
Curlian described this as bioplasma, an image of what he called the life energy of the object.
Scientists call this effect a corona discharge, and you get the same result using any conductive object.
It does not have to be alive.
Testing Aura Cameras Rigorously 00:07:14
A coin will work just as well.
Corona discharges have been well understood since the 1700s, and they have nothing to do with life energy or the psychic state of an object.
Finally, we have the latest, greatest, and stupidest of aura photography techniques, which was developed in 1992 by an electrical engineer named Guy Coggins, and is called the Aura Cam 6000.
This produces brightly colored pictures showing the person with superimposed, brightly colored clouds of light around them.
To take an Aura Cam picture, the subject sits and rests his hands on the leads of a galvanometer, the same device that Scientologists call an e-meter.
The Aura Cam takes a conventional photograph of the person, which is loaded into a computer.
The computer software then synthesizes an image of colorful clouds said to be based on the galvanometer measurement.
This colorful halo is then superimposed onto the image of the person, then it's printed out, and presto, you have your mysterious aura photograph.
In a world that can feel overwhelming, spreading thoughtful, evidence-based content is one of the best ways to make a positive impact.
Ask your local public radio station to air the Skeptoid Files, a 30-minute radio-friendly version of Skeptoid that pairs two related episodes promoting real science, true history, and critical thinking.
And in these challenging times for public media, we're offering these broadcasts for free to radio stations, available on the PRX Exchange or directly from Skeptoid Media.
It's an easy ask.
Just send a quick message to your station's programming director.
By helping to bring the Skeptoid files to the airwaves, you'll help promote the essential skills we all need to tell fact from fiction.
Just go to your local station's website, find the programming director's email address, or just their general email address.
You can even use the telephone.
I know that might sound crazy.
It's an old legacy device that allows real-time voice communication.
I know that's weird, but hey, it's an option.
The world can feel chaotic, but you're not powerless.
When you promote critical thinking, you can help your community tell fact from fiction.
And that's how we shape a better future.
In uncertain times, spreading good ideas can make you feel helpful, not helpless.
Let's stand up for reason, truth, and understanding.
Together, get them to air the Skeptoid files from Skeptoid Media, available on the PRX Exchange, and they'll know what that is.
According to Coggin's website, our technologies produce an electronic interpretation of what we believe the aura would look like.
It does not photograph the actual aura.
There's nothing that exists which can do that.
And how about those colors?
How are they determined?
Coggins actually gives several different answers on his website, that the colors are determined by corresponding electrical frequencies, that the colors were chosen in consultation with psychics to produce the same colors seen by psychics, and that they are based on the writings of Dr. Max Lusher, correlating personality with color preferences.
I guess you can take your pick of how you prefer to believe the colors in your picture were determined.
To Coggin's credit, his website is very clear that these images are not suitable in any way for making medical diagnoses.
Really?
And that they only represent the software's interpretations of the galvanometer reading.
He is also very clear that these devices are primarily for making money taking pictures at fairs, and he provides pricing guidelines and lists of events where you might choose to take your aura cam.
I wish that all peddlers of pseudoscience were that honest.
Joe Nicol wrote an entertaining account of having his own picture taken at a psychic fair with an aura cam in Skeptical Inquirer magazine.
So an examination of aura photography reveals no useful, testable evidence that auras even exist at all.
If we can't establish any reasonable foundation of evidence that they might exist, it's premature to address our second question, whether any useful information can be derived from studying auras.
So let's look at our third question.
How might it be possible that some people can see auras?
Nobody has ever suggested a plausible mechanism for how such a thing might be possible.
But if it is, there's a fat chunk of dough sitting there waiting for anyone who can do it.
James Randy has a million dollars in his vault that's yours if you can see auras.
Nobody has tried since 1989, when the prize was only $10,000.
On the TV show Exploring Psychic Powers Live, a psychic claimed that the auras she could see stretched five inches beyond the person and that she could see the aura extend beyond the top of a screen that a person was behind.
Ten screens were presented and by prior agreement between her and Randy, she needed to score 80% correct predicting which screens had a person behind them.
Random guessing would have resulted in a score of 50%, but she scored only 40%.
Can you or someone you know do better than that?
If you can, Skeptoid can qualify you to apply for the million-dollar prize.
Just come to the skeptoid.com website and click on the $1 million paranormal challenge.
Since that highly publicized failure on live television, author Robert Bruce, in his book, Auric Mechanics and Theory, has taken the classic step of moving the goalposts.
He states that auras cannot be seen in complete darkness or if any part of the person emitting the aura is obscured.
This special pleading presumes that auras have some quality that places them on a higher plane than what might be testable using basic blinded experiments.
So what it all boils down to is that the only supporting evidence for the existence of auras is the logical fallacy of special pleading that claims they are beyond the threshold of detection for anyone except self-described psychics whose claims must be allowed to be untestable.
Well, that's bogus and it's childish.
If Robert Bruce had anything in his book that could withstand any kind of scrutiny, he could easily be a million dollars richer.
Until aura advocates make some kind of reasonable, quantifiable description of their phenomenon, any discussion of auras, including their photography, their meaning, or their paranormal detection, should be treated with extreme skepticism.
