The photos were taken by Official White House photographer Pete Souza. Occasionally, photo (for example, this one) has EXIF information left untouched. Apparently Pete is a Canon guy, shooting with a Canon EOS 5D Mark II. Nikon should really send Pete a free D3X.
In the photo above: President Barack Obama and First Lady Michelle Obama wear 3-D glasses while watching Super Bowl 43, Arizona Cardinals vs. Pittsburgh Steelers, at a Super Bowl Party in the family theater of the White House.
