Experts in video effects said Mr Obama's talk on boosting employment had actually been recorded in front of a neutral "green screen" and the factory background filled in later. They said the edges around the president's head and shoulders were too sharp.
"The shot is obviously a composite and a 'weatherman quality' one," one professional in the field told BigGovernment website. "President Obama doesn't blend into the scene at all."
The White House denied the accusations. The claim followed a recent case where Michelle Obama was photographed shopping in everyday wear in a branch of the mass market Target store where an AP White House photographer conveniently happened to be.
