I love the creative ways that Chief White House photographer Pete Souza photographs the President and First Lady. He really adds an artistic flair to his photojournalism. (Above is what you call contre-jour.)
In case you didn’t know, the White House has a Flickr photostream where you can see images since the beginning of the administration. Most are of President Obama, but Michelle Obama is included in there, some photographs by Souza, some by her photographers.
