The all new micro-controlled Ghost Detector light works on a split and mix spectrum.
The unit works in conjunction with full spectrum camcorders.
The Idea of the ghost detector light, is that we don’t see in the ultra violet range or near infrared, we can see in the visible spectrum of light which is a very small portion of bandwidth of the whole electromagnetic spectrum, infrared and ultra violet is just outside each end of our general range, however our cameras can see in parts of this spectrum. Our most noticable colour is a greenish yellow colour, which peaks at around 555nm, and drops off quite rapidly for other colours.
When you look at Most Haunted and programs like that there’s always a green hue in the background, the reason for this is because if a shadow is cast against this light level, we are more likely to see it, Not meaning the night vision just the studio lighting etc. Same principle for safety jackets, and work coats etc, it is generally the most noticeable colour.
