What is a Full Spectrum Camera?
By: Sara Fawley
I have heard the term Full Spectrum Camera used many times as I am sure most of us have. I have some vague idea that it somehow captures from a light spectrum not visible to the human eye but that is as far as my limited knowledge goes. Due to this I thought I would do a little digging and see if I could explain it a little further for myself and anyone else who might be curious.
What I have found is this. A camera has a CCD sensor which in essence is it’s “eye”. This sensor controls how your camera “sees” the world around it. The sensor can only “see the visible light spectrum. Now there are other spectrums out there, the near infrared (IR) range and the UltraViolet (UV) range, that the human eye cannot see and that is also blocked out on your camera by an internal IR-cut filter in the camera’s lens. To make a camera “Full Spectrum” this filter is removed. Now the camera can not only “see” what the human eye sees but also the ranges beyond that. The theory is that these “invisible” ranges may be where spirits are “visible”.
What are the advantages to using a Full Spectrum Camera in the course of investigating?
The first advantage would seem to be that you do not need to use a flash in dark areas. While IR is invisible to the human eye it is very bright to the full spectrum camera.
The obvious advantage to no flash is that investigators are not constantly being blinded by the bright flash going off which can cut down on the tricks your eyes play on you in a changing light environment.
Another advantage is that environmental contamination “orbs” such as dust, lint, pollen and moisture are not going to be such an issue. These “orbs” are cause by the particulate being caught in the flash close to the lens. The only way this can happen with a Full Spectrum Camera is if the IR light source is to close to the lens. Keep the light source away from the lens…. problem solved.
Are there any disadvantages to a Full Spectrum Camera?
The major disadvantages that I found were that you cannot use them in the daytime or natural light because they cast a pink glow over the picture. The other thing I found is that you must have an IR light source and this can be a little costly.
So do Full Spectrum Cameras capture images of spirits?
We all know there is no conclusive proof of spirits or ghosts or anything else paranormal for that matter. To my knowledge to date there are no 100% proven photographs of spirits, full spectrum or otherwise but we keep pushing forward and trying to get that Holy Grail. If using everything technology has to offer us can get us there I say why not try.
