Ectoplasm Ghost Picture: Tuberculosis Hospital

Betty V. sent us this ghost picture of what looks to be ectoplasm manifesting in front of an old Tuberculosis Hospital. Is this evidence of a ghost manifesting with them?

" was a TB hospital, and Indian burial ground. It was said that the pond in front was haunted by a little girl."

The photograph was taken in 2002, and we believe the location to be in New York State.
