    The image above was captured using an 
    Olympus OM2 35 mm film camera. 
The camera was mounted on a steady tripod.
A shutter release cable was used to eliminate camera shake during the 3 second 
    exposure.
The picture was taken at night in a room 
    that was completely dark. 
No flash or auxiliary lighting of any kind was 
    used. Again, the room was completely dark.
 
In other words, the image on that particular frame of film should have looked like this:
     
    Completely blank -- which is exactly what every other frame on that roll of 
    film did look like,
    after being exposed under similar conditions of total darkness in other 
    rooms of the same building.
The photographer (me) did not observe any visible light or unusual effects at the time the photo was taken.
    Examination of the film negative 
    confirms that the image in question was indeed something that
    was "seen" through the lens of the camera and that it was not a result of 
    light leakage or processing error.
    
    And even more significantly:
 
The camera lens had been fitted with a special UV Transmission Filter.
    A  UV  transmission filter, also called a  UV  pass filter, blocks the wavelengths of visible light 
    while allowing the shorter wavelengths of ultraviolet light to pass through to the film. 
    Specifically, the filter used was a Schneider Optics B+W 403, aka a "black filter"
    with a spectral transmission range illustrated in the following graph:
    
    The wavelengths of visible light range from ~ 700 nm (above infrared) to ~ 400 nm (below ultraviolet).
    
    The # 403 filter's transmission factor is essentially 0 within 
    this rather narrow range of visibile light,
 but it passes a high percentage
    of the ultraviolet. There is also a secondary 
    pass window in the infrared range.
    Standard photographic film is extremely sensitive to 
    ultraviolet light but is not affected by infrared.
    Therefore, an image captured on standard film when using the # 403 filter provides strong indication of ultraviolet exposure -
    either directly from a UV emitting source, or indirectly by reflections from 
    such a source.
    
    
    
    Longer wavelengths correspond to 
    lower frequencies, shorter wavelengths to the higher, "more energetic" 
    frequencies.
 The wavelengths of light are expressed in nanometers (nm), corresponding to billionths of a meter.
    For comparison, the wavelengths from an FM radio station's transmitter measure about 3 full meters. 
    Ultraviolet and infrared wavelengths are not visible
    to normal human eyesight.
    Like stations just beyond the range of a radio dial, they're out there, 
    but you can't quite tune them in.

The key point I'm asking you to recognize is this:
UNLIKE every other alleged "ghost" picture or so-called "orb" photo you may have seen before,
    the photo above was taken under tightly controlled 
    conditions as part of a well planned and carefully executed
    test of a specific hypothesis. This hypothesis proposed an exotic but 
    scientifically credible explanation for
    the occurrence
    of a certain type of photographic anomaly that sometimes appears in otherwise 
    ordinary 
    pictures.
    The 
    hypothesis was basically this, a two-parter:
    
    1) Certain "unknown energy forms" exist in our world but they are ordinarily 
    invisible to humans.
 2) These energy forms emit UV light and should therefore be detectable 
    using simple photographic techniques.
    This hypothesis was based on my examination of 
    numerous photographs showing peculiar streaks
    and diffuse "fog" effects, usually white or bluish-white in color. Such 
    effects have been obtained by many
    people going back to the early 
    days of photography. Could these mysterious effects, effects that people
    who were present when the photos were taken did not see and could not 
    account for afterwards,
    possibly be the result of ultraviolet emissions produced by an unknown 
    energy form?
    Knowing that standard photographic film is very 
    sensitive to ultraviolet light,
    that ultraviolet will appear as white in black & white, and bluish-white in 
    color film photos,
    and that UV light is invisible to humans, I knew that my Ultraviolet 
    Hypothesis could serve to
    explain an entire category of photographs that I was repeatedly coming 
    across in my studies of the paranormal.
    Furthermore, I knew that animals, including cats and 
    dogs, have a range of visual perception that goes beyond
    that of humans, thus certain strange behavior occasionally observed in these 
    animals and often attributed to
    paranormal stimuli ("they're seeing a ghost") might also be explainable in 
    light of my Ultraviolet Hypothesis. 
    In effect, our animal friends may sometimes be seeing  things that are out of the 
    ordinary but quite real,
    something perfectly obvious to them, yet completely imperceptible to us, 
    something potentially paranormal.
    Along similar lines, there have been many 
    anecdotal reports of people witnessing a variety of mysterious
    light phenomena, including accounts of floating and moving "balls of light" 
    which are often said to be blue or
    bluish-white in appearance. This type of phenomenon might well be related to 
    the energy forms seen in the photos
    presently under discussion. The rare visual sightings could be accounted for 
    if the effective wavelength
    exhibited by these phenomena is variable, sometimes dropping out of the UV and 
    into the visible range.
    Remember too, some individuals have a range of color vision that extends slightly 
    higher or lower than the norm,
    this "gift" allows them to see a bit beyond the rest of us and into those 
    normally invisible fringes of the spectrum.
    These hypothetical variations, either in the 
    phenomenon's wavelength or with an individual witness's vision,
    could also offer an explanation for the sporadic and non-universal 
    nature of being able to see a "ghost".
 
    SO . . .
 
    With these facts and speculations re a 
    possible UV-Paranormal correlation in mind,
    I realized that my Ultraviolet Hypothesis could be put to an objective 
    scientific test
    using readily available and relatively inexpensive photography equipment.
    
    After a few encouraging early attempts, and many 
    more discouraging ones that resulted in nothing but the
    predictable rolls of blank film, I finally succeeded in capturing this 
    remarkable photograph on November 14, 2003 
    at the Exchange Hotel and Civil War Museum in Gordonsville, Virginia -- a 
    site where many strange encounters
    and mysterious phenomena have been reported over the past 150 years or so.
    
Let's take another look at it:
    
    
    At this point, please let me make it perfectly clear that I am not trying to 
    claim this is the first "authentic" 
    photograph of a "ghost" or "paranormal energy form" that's ever been taken, 
    however, to the best of my knowledge:
    IT IS THE FIRST PHOTOGRAPH EVER TAKEN THAT 
    CANNOT BE ANYTHING OTHER THAN
    
    A  "PARANORMAL ENERGY FORM"
Let me repeat that:
    
 
    THIS IS THE FIRST PHOTOGRAPH EVER TAKEN 
    THAT CANNOT BE ANYTHING OTHER THAN
    
    A  "PARANORMAL ENERGY FORM"
    That might seem like a rather brash and sensational 
    claim,
    just one more in a field where brash and sensational claims are so 
    commonplace
    it's hard to navigate your way around them without wearing  very high 
    boots.
 
However,
    I can make the statement above with a  high degree 
    of confidence because I know that 
    it is a conclusion based on the principles prescribed by the time-honored 
    scientific method.
    Note: I'll have much more to say 
    about the scientific method elsewhere on this website, but to summarize,
    the essential steps are: Observation > Hypothesis > Experiment > Conclusion.
The most critical and distinctive step in the scientific method is:
The Experiment.
    This is also the step that pseudo-scientists prefer to 
    ignore.
    The "pseudoscience method" tends to jumble observations (if any), 
    hypotheses, and conclusions
    all together in an untested -- perhaps even un-testable -- mix of 
    speculation and fantasy.
Where's the experiment ?
In science, conclusions follow only from properly executed experiments that test the validity of a hypothesis.
    With the experiment, hypotheses are validated or 
    rejected. Conclusions follow accordingly.
    Without the experiment, an objective test of the 
    hypothesis, there can be no scientifically valid conclusion.
 
    The current "standard model" of paranormal research 
    completely overlooks, or simply fails to understand
 the all-important step of testing a hypothesis through controlled 
    experiments. Running around inside a building with 
    a truck load of expensive high-tech equipment does not in and of itself 
    constitute a scientific experiment.
    
    Yes, this could be considered as part of the observation phase of scientific 
    research, but even that only as
    a discovery process whereby  preliminary observations 
    and base-line parameters are established.
    Unfortunately however, all too many paranormal researchers take what are 
    really a set of 
    preliminary observations and make the giant leap directly to 
    hypothesis=conclusion.
Where is the experiment ?
Let's take yet another look at this photo:
    
    I'd like for you to understand this photograph 
    as an example of how
    the 
    scientific method can be applied to problems in paranormal research:
1) Preliminary observations, thought, and study led me to formulate
    2) The hypothesis that an unknown and invisible energy 
    form capable of emitting UV light
    could be the cause of certain effects that sometimes show up in otherwise 
    ordinary photographs.
    3) To test my hypothesis, I devised an experiment in 
    which I would try to obtain photographs
    of the suspected energy forms by taking pictures in areas that were 
    completely dark,
    without
    the use of any flash or auxiliary lighting, and away from all possibilities 
    for contamination
    by ordinary light sources, or reflections, etc. My goal was to eliminate all 
    the "normal" sources of light
    that could conceivably cause effects similar to those being addressed by my 
    "paranormal" hypothesis.
    Furthermore, I applied an additional and very 
    significant level of light management
    to my experiment with the use of the UV transmission filter as previously 
    discussed.
    The "control" aspect of my experiment was 
    conducted by obtaining a large number of
    photographs in my own house and at other locations not 
    reported as being "haunted" while
    using the same conditions of darkness, same camera equipment, etc. 
     
    I also took many photos
    with the same camera equipment and  UV transmission filter under 
    variously lighted conditions in
    order to gain an understanding of the normal results that could be 
    expected with my set-up
    for comparison to any suspected "paranormal" results that  might be obtained in 
    a "haunted" setting.
    4) Subsequent observations of my recorded data (i.e., 
    looking at the developed film and pictures)
    confirmed one instance of a result that was not explainable by any known 
    means, therefore my
    original hypothesis re the existence of an unknown UV emitting energy form was 
    scientifically validated.
BTW,
    Please note that although I've used the term "ghost" 
    earlier in this article, that was just a convenience.
    Same for the term "paranormal energy form" since I'm still struggling to 
    figure out what "paranormal" means.
    
    I can't claim that I've "proven ghosts exist" or even that "the 
    paranormal exists", but ...
    
    I can be certain 
    that I have obtained scientifically credible evidence for an unknown energy 
    form 
    that emits radiation having 
    characteristics
    consistent with ultraviolet light emissions. 
    Since there are no known  emitters of UV light
    that should be flying around inside a building at night,
    I have dubbed the 
    phenomenon
 
Energy Form X
For those familiar with the famous "white crow" statement of Professor William James:
    
    "To upset the conclusion that all crows are black ... 
    it is sufficient to produce one white crow; a single one is sufficient."
    
    You will understand that 
    my one instance of a positive result for 
    Energy Form X
    is sufficient to prove the case -- assuming of course that this one 
    instance is indeed what it appears to be.
 
    I am personally quite 
    confident that it is -- 
 
But you should not be !!!
    
    huh ???
    Well, I do think you should 
    be excited about my experimental results, but at the same you should also
    be prepared to question, challenge, and above all, attempt to replicate the 
    results of my experiment.
    In science, replication of 
    the results of an experiment is always sought in order to strengthen the 
    case
    for the conclusions advanced, and to seek an ever better understanding of the 
    phenomenon in question.
    (Alternatively, attempts at replication can also serve to falsify or 
    disprove an erroneous conclusion.)
    After obtaining my 
    remarkable photograph at the Exchange Hotel in 2003, I was determined to try 
    and
    reproduce the result. I took many more photographs with my UV camera 
    equipment at various locations,
    including an intense all-nighter return session at the Exchange. I devised a 
    method for using inexpensive
    Kodak "Hawkeye" cameras  modified to accept UV transmission filters 
    and loaned these out to
    fellow researchers for further experimentation, but despite all these 
    efforts, neither I nor my
    associates were able to obtain any additional evidence for the existence of
    Energy Form X 
    . . .
UNTIL . . .
    Almost a year to the day 
    after the photo at the Exchange Hotel and Civil War Museum was taken, 
    this photo was obtained at another Civil War related location, the
    Andrew Johnston House in Pearisburg, VA,
    also a site of various unexplained happenings:
    
 
    
    For this picture, I was using black & white film of a 
    type that is especially sensitive to UV.
    Although not as dramatic looking as the Exchange Hotel photo, it does 
    appear to show the same
    phenomenon, but this time Energy Form X 
    was apparently located several feet farther away from the camera.
    
    Otherwise, the characteristics of the photographed 
    phenomena are quite similar, both show a
    tightly focused "core" of moving energy and a more nebulous or  misty 
    area swirling around it.
    You should also be aware that in both pictures, the 
    display of UV light must have been quite intense and
    highly concentrated since the glass lens
    of my camera, in conjunction with the UV transmission filter,
    would actually allow only a relatively small fraction of the available ultraviolet light to  reach the film.
    As before, the second photo was taken at night inside a 
    dark building using a 35 mm camera and UV pass filter.
    My fellow investigator and I had gone outside but we remained nearby to 
    monitor the building while a
    30 minute exposure was being made with the tripod-mounted camera in "bulb" 
    mode. 
Here are both photos again, side-by-side for comparison:

Further Thoughts:
    Excerpt from:
    
    What do dogs see? A review of "Vision in dogs" 
"Vision in dogs", was written by Paul E. Miller, DVM and Christopher J. Murphy, DVM, and published in the Journal of the Veterinary Medical Association (JAVMA, vol. 207, no. 12, pp. 1623-1634, Dec. 15, 1995).
A number of studies have been done to investigate the color vision of dogs, and the results have been conflicting. However, more recent, better controlled studies indicate that dogs do possess and use color vision, but not to the same degree that humans do. The photoreceptor used for color vision is the cone, and there are cones present in the canine retina. However, they are present in low numbers, comprising less than 10% of the total photoreceptor population in the central area of the retina, as opposed to the human retina which consists of nearly 100% cones in the fovea. Two distinct type of cones appear to be present in the canine retina. One type is maximally sensitive to light in the wavelength that appears violet to people, and the other type is maximally sensitive to light in the wavelength that appears yellow-green to people. Thus, it appears that the visual spectrum of color in dogs is divided into two hues; one in the violet and blue-violet range, probably appearing as blue, and the other in the greenish-yellow, yellow, and red range, which is probably seen as yellow. Light that appears blue-green to people probably appears as white or shades of gray to dogs. Dogs are unable to differentiate colors that appear as green, yellow-green, orange or red to people, and are unable to differentiate greenish-blue from gray. This is similar to people who are red-green color blind. However, one study indicates that dogs are better able to differentiate between subtle shades of gray than people, which would be advantageous in increasing visual discrimination in low light conditions, where insufficient light is available to stimulate cones.
The authors conclude by stating that although the canine visual system may be considered inferior to the human visual system in such aspects as degree of binocular overlap, color perception, accommodative range, and visual acuity, the canine visual system is superior to the human visual system in other aspects, such as functional ability in low light conditions, retinal response rate to another image (flicker fusion), field of view, ability to differentiate shades of gray, and possibly the ability to detect motion. The canine visual system is optimized to exploit a different environmental niche than our own, and hopefully by better understanding the strengths and weaknesses of the canine visual system we will be better able to understand our hunting companion's capabilities. Let me conclude by encouraging those of you interested in this issue to read the complete article, which includes 68 references to other works.

AND NOW, CAT VISION:
From: http://www.kittyshow.com/x_cat_vision_color.htm
Cats responded to the colors purple, blue, green and 
yellow range. 
Red, orange and brown colors appear to fall outside cats color range and are 
most likely seen as dark to mid shades of gray.
Cats appear to see less saturation in colors than do humans, meaning cats do not 
see colors as intensely or vibrantly.
Purple, blue & green appear to be the strongest colors perceived by cats.
[Still looking for something to 
confirm whether or not dogs & cats can actually see into the UV range, but for 
now it's clear
that both do have good color vision in the violet and blue-violet range. Note 
that although it's said these animals don't perceive
some colors, that doesn't mean they don't see anything at those wavelengths, 
only that it appears as shades of gray to them.  JH]
