Adding a Ghost to a Photograph
Add a ghost to your photograph and make the photograph poor quality just like the most famous photographs of ghosts.
Photographs of ghosts are usually very grainy and unsaturated. Ghosts tend to be overexposed and translucent with their transparency differing depending on the brightness of the object it is in front of, however, that is only a stereotype and there is no evidence of what a ghost should look like. Photographs of ghosts seem to appear most haunting when they the picture of the ghost wasn't taken deliberately; perhaps with someone in the photograph smiling at the camera and unaware of the ghost.
