The following nice vortex ghost picture was sent by Linda. Is it a camera strap? Looks a bit small for it to be the strap of the camera.
"I have always had an interest in ghost photography and have been on many ghost hunts. The only luck i have had in catching any, comes from the house I live in which is haunted. You can see distinct diamond shapes within the vortex. Linda, Christmas Eve - 2003, Shakopee , Mn."
