What is a Full Spectrum Camera? How can it be useful as a Ghost Hunting Camera?
Full spectrum camera conversions are not difficult to understand. A normal digital camera has a CCD (or CMOS) sensor that is
only allowed to "see" the visible light spectrum, up to about 750nm. The near Infrared (IR) range, approximately 750nm - 1200nm,
is mostly blocked out by an internal IR-cut filter inside the camera lens. By removing the IR-cut filter, the camera's sensor (its "eye")
is allowed to see a broader spectrum beyond what the human eye can see. What might be hiding in the invisible Infrared
spectrum? This camera can see what we see plus what we cannot. Note: Our full spectrum cameras do not have the visible
spectrum filtered out. True full spectrum cameras include the visible spectrum.
What are the advantages of the full spectrum cameras we create?
1) A flash unit is not needed in dark settings if an Infrared light source is used.
Infrared is invisible to the human eye, but to the full spectrum camera it appears
very bright. Without using the flash unit, the full spectrum camera can become your
eyes to see into dark environments.
2) The full spectrum camera and Infrared light source will not disrupt the
environment, which maintains the integrity of the ghost investigation. The
investigator's eyes will be able to see better in the dark conditions, not being
blinded by the constant popping of the flash unit. You can even work without using
a regular flashlight by carefully watching the full spectrum camera's LCD screen.
3) Orbs caused by dust, pollen, lint and moisture, which are created when the
particulate reflects the camera's flash unit in front of the lens, will no longer be a
problem. In other words, false orbs can only be photographed if the IR light source
is too close to the camera lens. If you keep the light source away from the camera
lens and still photograph an orb, there is a good chance that the orb is emitting its
own light source visible to the full spectrum camera. Read: Ghost Hunting
4) You have three Infrared light sources to choose from:
- An infrared illuminator sold for use with video cameras that have night-shot
- An infrared flashlight
- An incandescent black light bulb (which emits infrared - this is not the fluorescent
All three light sources emit Infrared light that will illuminate the environment for the
full spectrum camera. The black light bulb is a great method to use in buildings with
A/C power. The IR illuminator and IR flashlight require batteries but can go
We have found with full spectrum cameras that the stronger the Infrared light
source the better they will be able to see in the dark, having a much more clear
image. Light is directly related to image quality. While our full spectrum cameras
and video recorders will see Near UV (such as with a UV flashlight), in low-light
conditions while ghost hunting, it is best to use Infrared light sources. Of course, all
of our models of camera can see the expanded range of light from Near Ultraviolet
to Visible to Near Infrared.
All sorts of light may be experimented with, of course, especially combinations of
light sources. However, this can create multiple shadows and confusing light
patterns that may make discerning paranormal evidence more difficult than
sticking with Infrared.
We should also mention that our cameras and camcorders can be easily switched
back and forth, from full spectrum to Infrared, if you purchase our IR-Pass Filter kit.
By blocking the visible spectrum, the IR Pass Filter turns the full spectrum camera
into an Infrared unit in a snap!
