This is what happens when you use the wrong shutter speed while taking a picture. Many people don’t realize this and think that these are images of the paranormal.
Using the wrong setting with quick movement of the camera can cause this ghostly type effect.
This next photo was taken on an investigation on the south border going into Mexico.
I snapped this photo when it was 23 degrees with high humidity. You can see the ectoplasm effects this has on a photo. Always be aware of your surroundings and camera settings on an investigation. It was nothing more than my exhale of breath creating this ghostly photographic mistake.
