Few jobs look cooler on a business card than "Official White House Photographer." But that's precisely the job of Pete Souza, the professional photographer who's spent the last eight years documenting Barack Obama's daily life in the Oval Office.

"When you add up (the president's) day, and all the things that I photograph, I take a lot of cool photos," said the photographer in a short interview for BBC Newsnight. "Someone in my office who monitors this said that I'd probably end up taking, at the end of eight years, two million photographs."

Souza, who was also Ronald Reagan's official photographer from 1983 to 1989, actually took his first pictures of President Obama back in 2005. "He's walking around Red Square, he's on a sidewalk, and nobody knows who he is," said the photographer. Just four years later, however, Obama was elected as the 44th President of the United States.

Take a look at some of Souza's amazing pictures below - this is how a day in the life of Barack Obama looks like. You can find more from this photo series on the Official White House Flickr account. (h/t: PetaPixel)
