ah i do like a good discussion about these things.
perhaps at some point youll get to see what our team have captured on film and i wonder if any would get you thinking more about the existance of something close to what people class as ghosts.
btw, ratter, night vision can be good, it can also cause extra shadows and loss of focus. We always have to use booster lamps on our camcorders as it will not fill room with light just using the built in IR light.
