It’s believed Pete Souza has snapped 2 million pictures of the former President. These are his best.

As the world waves goodbye to Barack Obama as President of the United States, the official White House photographer, Pete Souza, has revealed his favourite 55 pictures from Obama's time in the White House.

From candid shots with his family to adorable pictures with babies, these pictures are guaranteed to make you melt.

It’s believed Pete Souza has snapped 2 million shots of the current President. These heartwarming moments show Obama's softer and funnier side, although a few pictures selected also show huge moments in history such as the President waiting to hear the outcome of the May 2011 mission to kill Osama Bin Laden.

Souza's 'Year in Photos' albums on the White House Flickr account show his favorites and go back to 2009. Fifty-five images of the president were compiled by Twisted Sifter.
