Photo Tampering Throughout History
 

Photography lost its innocence many years ago. Only a few decades after Niepce created the first photograph in 1814, photographs were already being manipulated. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of photos is becoming more common. Here, I have collected some examples of photo tampering throughout history. To help contend with the implications of this tampering, we have developed a series of tools for detecting traces of photo tampering.
