Secondo Pia’s Flashbulb

Origin
Secondo Pia was an amateur photographer who took some of the first pictures of the Shroud of Turin. While developing them, he made a startling discovery: on the negative there was a second image. It was a clearer image of a man’s face that was invisible to the naked eye. The image he obtained from the shroud has been approved by the Roman Catholic Church as part of the devotion to the Holy Face of Jesus.

Effects
The picture of any scene can be transferred from the film onto an object’s surface. The first picture will create a faint image undetectable to most people. Repeated snapshots over the same area will etch that picture in deeper, creating a physical etching. The affected object will concentrate unnatural attention onto itself, causing obsession within onlookers.
