Real or Fake 1

Yet another new thread of topics during my many searches on the net and in real life, I have come across many pictures of so called 'ghosts' so I have decided to post some here over time under the title real or fake.

I can normally tell which are which but at this point if I say to much will give away the clues, so here's the first one.........real or fake?

Here is a famous example taken in 1936 at Raynham Hall in Norfolk. Some say it shows a ghost, others that it is a trick of the light or even a fake.
