Well just as an addendum. I was e-mailed the original photos, for some reason the uploaded ones had the EXIF camera data stripped. But I did get the original in its original resolution without being cropped. And the original also had the same images in it.
So I would have to conclude that barring any other evidence this is a real capture of something paranormal on a photograph. EXCELLENT catch! Its amazing that an image which was not part of an investigation but rather part of another project would turn out paranormal evidence.
I noticed on the other images that it seems to be a english style garden. Can I ask what part of the country this is in? I almost spot what appears to be a crypt or stone building in the far background.
