THERE IS A PHOTOGRAPH of Barack Obama, taken by the official White House photographer, only minutes before his first inauguration. Obama stands before a mirror. His reflected expression is intense, but ambiguous. Depending on your interpretation, the former Illinois senator looks dignified and confident--or paralyzed with fear. At that very moment, millions of Americans were waiting to see their new president address the nation for the first time. What sort of a person were they going to see?

The first year of the Obama presidency generated a stream of photo ops that pushed a clear editorial line. Images of the president hobnobbing with George Clooney, Bruce Springsteen, Robert De Niro, Bono, and Beyonce began appearing on White House Flickr and Instagram pages. Photographers on the presidential payroll depicted Obama as a larger-than-life figure, respected by leaders abroad and BFFs with celebrities at home.
