The light we see
is known as "white light". It's really a combination of all visible colors of
the spectrum. "Visible" being the key word. The total light spectrum is much
larger than what we see. In fact visible light is only a tiny fraction of the
Visible light is part of what is knows as the Electromagnetic Spectrum. The
spectrum starts with longer wave/lower frequency light on the left side which
includes the infra red lights, radar, FM/AM and television signals followed by
the narrow section of humanly with the naked eye visible light, through to the
shorter wave/higher frequency ultra violet lights, X-Rays and Gamma Rays on the right
end of the spectrum Yes, radio, television and radiation are all part of the
same electromagnetic spectrum as visible light (they all forms of light, just
that we can't see it with the naked eye).
Below are two diagrams that represent the full range
of the EM spectrum:
It has long been theorized that entities, spirits, ghosts etc may be more visible in other
light spectrums than the normal narrow range of visible light.
light has long been used for night vision video cameras. IR light is invisible
to the human eye so it does not disrupt a location the way shining a bright
flash or search light would. It also doesn't effect investigator's night
vision (that's why we also use red filters on our flash lights as much as
possible). Camcorders and DVR cameras usually come with built-in IR
illuminators and additional higher power illuminators can be purchased. Night
vision viewers, monoculars and binoculars also usually have IR illuminators
built-in. There are also IR film cameras but they require special film and
processing, and is generally more expensive and complex to operate.
IR light is often
confused with heat/thermal imaging. They two separate things. While heat is a
form of IR light, an IR camera is designed to see the light not the thermal
and visa versa. Also, colors seen in IR can be very different from visible
light. For example, what appears black in visible light is usually bright
white in IR. And IR has an element of "x-ray vision". Some materials that do
well to be opaque to visible light are transparent in the IR spectrum.

Notice the differences in the view between visible (picture above) and IR light!
of the easily obtained IR cameras and illuminators paranormal investigators
have been using IR for years in their research. Many good images and video of
potentially haunted or paranormal activities has been documented with IR
light. The main draw back to using IR light is that it takes a really large IR
illuminator to fully illuminate a big area. And IR cameras are very sensitive
to small objects. Dust, pollen etc are frequently seen on IR cameras and can
easily be mistake for orbs.
UV (aka "black
light") light hasn't received much review in paranormal research, probably
because it isn't as easy to generate and use as built-in IR illuminators. Some
paranormal investigators have reported that certain brands of night vision
camcorders are very sensitive to UV light. It has been reported that using a
UV light source with the camera in night vision/night/shot mode illuminates
much better then in regular IR night vision/shot mode. To date, however, we
have not seen any significant improvement in collecting paranormal evidence by
using UV light instead of IR light. Further research is being conducted.
Brian Harnois and Paul Donovan give LIPI members a tour of TAPS headquarters
and exchange approaches for paranormal investigations and equipment use.
Island Paranormal Investigator's first meeting with TAPS (The Atlantic
Paranormal Society) the topic of IR verses UV light was discussed with TAPS
investigator Brian Harnois. Brian told LIPI that TAPS had experimented with
UV light for paranormal photography and videography during their ghost
investigations. He said they too found little evidence that UV worked better
than IR. Interestingly though, he did say that when investigating cases of
alleged demonic hauntings TAPS found that UV light acted as a barrier to the
demonic entity; The entity seemed to avoid crossing doorways and threshholds
that were illuminated with UV light. Brian said research on this is
continuing. (Click Here for further information about
LIPI meeting with TAPS)

Based on research
and discussions it appears that entities, ghosts, spirits etc. are more
sensitive to being seen in IR light than UV light. This is in line with
another theory that ghosts move very quickly through our space. A high speed
object would be better illuminated with a low frequency/long wave light
source than a high frequency/short wave source. It is also possible that
whatever the composition of ghosts is (including ectoplasm) is more sensitive
to reflecting IR light.
Additional research and investigation on this subject is being conducted by
LIPI and other paranormal investigators.
