Some say this Japanese schoolgirl photo shows an evil spirit. Others say it's just bad Photoshop. Everyone agrees that it's pretty freaky. The photo apparently shows a brochure for a private high school in Miyagi prefecture. As awful as it sounds, look under the desk.
Yikes! This image has been retweeted over 4000 times, with people online calling it "shinrei shashin" (心霊写真), which means "spirit photography" or "ghost photography". Other folks are pointing out that, obviously, this is probably just a Photoshop screw-up. A creepy one though!
It's likely that the originally photo showed the student with bad posture with her hand hanging in her lap. So, it was tweaked, giving her good study posture — forgetting to remove the original hand!
The brochure image, however, has apparently been fixed, with the new photo seeming to erase the spooky appendage, and even tweaking the schoolgirl's hand on her desk.
