May 5, 2011: Ghost of executed murderer

[glatt]

I think the assistant was holding the monitor in front of them, so the assistant stayed in the relative darkness. Then after the image made it into the camera from the monitor, they could shoot off a flash to illuminate the whole scene without the assistant in the shot. The only light source during the time it took to make the image was probably that street light, but if they set the exposures right, they could have made it so the assistant wasn't lit up enough to appear in the final image.

I'm probably not explaining it too well, but it's all about controlling the exposure levels and having the assistant move around. No photoshop needed.

edit: A similar trick is to make a busy highway appear to have no traffic on it by taking a long exposure. Like this.

This may not be a good thing, either he(it) will come back 1871 times to haunt us or "Ghost Hunters" will have a 1,871 marathon (one hour for each slice.)

I bet some of the diagonal streakiness on the large light area of the side of the house is the assistant.
