Photojournalist Pete Souza served as the presidential photographer for both Ronald Reagan and Barack Obama. In an interview with Pulitzer Prize-winner Marcia Nighswander at Ohio University, he tells the story behind several of his most noteworthy images from the Obama presidency. Some of his most memorable photos of Obama were taken at the Christ the Reedemer statue in Rio and while crossing the Edmund Pettus Bridge in Selma, Alabama.

Souza has a popular Instagram account and will be publishing a book with 300 photos from the eight years he spent in the Obama White House.
