These have been on the internet before, they are from 2008 and in the past we did a lot more and have other films of different places. An American friend who does a lot of ghost hunting with his wife and father and their ghost team, that I showed these to last week, thinks these are very good examples.
We originally came across them accidentally when using a certain kind of plug in web cam. This old web cam picked them up. Modern web cams that are attached to items can't do the same job for some reason or certainly not as well. We still have a couple of the old web cams which we keep to plug in for this kind of thing.
The only thing we noticed was that if anyone got in to shot with the orbs then that person became ill soon after. The same happened with an animal, a pet of the time, - so we keep out of the picture now if we do this kind of thing.
