We feel it equally important to this end to also discuss the legends and myths that have somehow worked their way into the mainstream of paranormal investigation, and how these can affect investigational objectivity. The theory is that anomalies that show up on videos and even possibly on film are composed of some sort of energy that is not visible to the human eye. It is possible that at least a part of this energy falls into the infrared spectrum of light, just beyond visible light. As such, a ball of infrared light energy could travel directly in front of your face and you would never see it. Modern video cameras however can see things that are beyond the spectrum of light that is visible to humans.
Many video cameras utilize CCD elements that are sensitive to infrared radiation.
One way to test this is by using an infrared remote control device from a television or other houshold appliance. You should not see any light being emitted by the element. Now, pointing the remote control towards the lens of the camera and pushing any button, look through the viewfinder of the camera. The odds are good that you will see a bright white light being emitted from the infrared element of the remote. Again, this is because the component within the camera which picks up the image and then sends it to be recorded on tape is sensitive to infrared light.
