A "Year in Photographs 2012," released by Pete Souza on Flickr Thursday, documents the past 12 months in the life of Barack Obama and the people around him. Souza -- who has been the chief official White House photographer since 2009 -- whittled down tens of thousands of pictures (he and his staff can produce up to 20,000 photos per week) to the most memorable and included some of the stories behind the photos. Here are some of our favorites from the impressive collection.
In the picture above, taken on May 19 during a G-8 summit at Camp David, Obama reacts to the winning goal in an overtime shootout of the Chelsea vs. Bayern Munich Champions League final along with British Prime Minister David Cameron, German Chancellor Angela Merkel, European Commission President José Manuel Barroso, and French President Francois Hollande.
