How Photoshop helped aid Chinese propaganda

The Wall Street Journal points out where this antelope photo has been manipulated in Photoshop

An award-winning photo showing antelopes playing in Tibet has been exposed as a scam, after Chinese web users discovered it had been doctored in Photoshop.

China's state-run news agency, Xinhua, issued a grovelling apology earlier this week after publishing the manipulated photo of Tibetan wildlife playing near a high-speed train, the Wall Street Journal reports.
