Reuters Admits to Altering Beirut Photo

A recent press release tersely noted:

“Reuters withdraws photograph of Beirut following Air Force attack after US bloggers, photographers point out 'blatant evidence of manipulation.' Reuters' head of PR says in response, 'Reuters has suspended photographer until investigations are completed into changes made to photograph.' Photographer who sent altered image is the same Reuters’ photographer behind many images from Qana, which have also been subject of suspicions for being staged.”

Hmmmm…faked war photographs? How is a news editor supposed to know these things? I guess it takes a real expert to determine that. For example, take a close look at the following photograph. To the average person it is just another pic of Beirut under attack. Reuters or AP would probably publish it in a heartbeat. But a true photographic expert can spot something that seems a bit unusual and marks it as a possible fake. Can you tell what that might be?
