Is this a photograph of a ghost? The Science Of Hauntings

An eerie image of a figure in period costume at a Scottish castle has spooked experts conducting the biggest ever investigation into photographic evidence for ghosts. The picture, taken in May 2008, appears to show a man or woman in a ruff peering out of a barred window at Tantallon Castle. No mannequins or costumed guides are employed at the castle, and three photographic experts have confirmed that no digital trickery was used on the photo. Tantallon Castle, a ruined fortress dating back to the 14th century, stands on a remote rocky headland near North Berwick on the Scottish east coast

Members of the public were asked to submit ghostly images for experts to analyse, the best of which were posted on the website www.scienceofhauntings.com
