This political advertisement for George W. Bush, as he was running for President, shows a sea of soldiers as a back drop to a child holding a flag. This image was doctored by cloning (copying and pasting) a group of soldiers.

Shown below is the result of one of our forensic exams that detects image cloning: the red, green, and blue regions denote cloned image regions (in this case, the same group of soldiers were cloned into two different locations).
