Digital Tampering in the Media, Politics and Law

From Hany Farid's website:

"Photography, of course, lost its innocence many years ago. In as early as the 1920s, shortly after the first commercially available camera was introduced, Stalin had his enemies "air-brushed" out of photographs. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of digital tampering in the media, politics, and the law."
