According to The Sun, a 14-year-old believes a picture taken in an ancient castle proves ghosts exist.

This seems like a pretty simple fake to me, though. Every digital camera I’ve ever used allowed me to set the exposure time. Long exposure times help to make up for extremely dim lighting, but anything moving through the shot will show up as a ghostly, blurry image. Someone walking down the steps and pausing briefly on the landing would produce this effect if the exposure time was set pretty high (which seems pretty likely to me — I would imagine that ancient castles are fairly dark).
