When the Obamas moved to the White House in 2009, their daughters Malia (left) and Sasha were 10 and 7. Personable and friendly, they were the epitome of the ordinary American family.

Barack Obama comes across as approachable and down-to-earth. During a family visit at the Oval Office, he readily bowed his head so the little boy of a White House employee could touch his hair: "I want to know if your hair is like mine."

The president and the first lady donned 3-D glasses to watch the Super Bowl at a party at the White House - in their very own movie theater.

The United States played Japan in the final match of the Women's World Cup soccer tournament in 2011 - a match that had the Obamas on the edge of their seats as they watched on TV. Pete Souza, the official White House photographer, captured this private family moment.

A gift from Senator Edward Kennedy, Bo the Portuguese Water Dog joined the Obama family in 2009. Four years later, Sunny, a female of the same breed, made the family complete.

Caught in Spider-Man's sticky web - oh no! The most powerful man in the world, always a good sport, plays along with the child of a White House staffer in 2012, just before Halloween.

... there's a great woman, as we all know. Who stands behind whom in the Obama family? America's first lady is more popular than her husband - her ratings are almost constantly at 70 percent, while the president's dropped to 40 percent at one point. The Obamas are regarded as a dream couple.

Many Americans adore Michelle Obama for juggling her role as "mom-in-chief" and the more political role of first lady. Above, she and a group of students are harvesting sweet potatoes in the carefully tended White House kitchen garden - a pet project.

The world follows her political engagement just as attentively as her choice of clothes. Always in the limelight, Michelle Obama manages to show style even sitting next to Elmo (left) and Rosalita. "What I have never been afraid of is to be a little silly, and you can engage people that way," she once told "Variety" magazine.

The first lady demonstrated this again in a clip for the cult series "Carpool Karaoke," which has received more than 50 million views on YouTube. While James Corden's car circled the White House grounds, Michelle Obama and Missy Elliott belt out "This Is For My Girls" for the cameras.

With such cool parents, Sasha and Malia sometimes display a little public coolness themselves. While their father was inaugurated for the second time as president in 2013, they posed for a joint selfie.

Malia celebrated her 18th birthday while still living in the White House. The outgoing US president used the occasion to show a less statesman-like side. "Just because it's the job of a father to embarrass his daughters, I've got one last job," he explained at the end of a speech - and launched into "Happy Birthday."

Barack, Michelle, Malia and Sasha Obama, now 15, are now moving out of the White House. But they are not yet turning their backs on the US capital; Sasha will still be attending school in the city. In the fall, Malia intends to begin studying at the prestigious Harvard University in Cambridge, Massachusetts.

Award-winning photographer Pete Souza has documented newsworthy events throughout his career, from the Kosovo refugee crisis to the start of the war in Afghanistan. In 2009, after spending time shooting Barack Obama on the campaign trail, he took on the role of official White House photographer — and gained more access to a sitting president than likely any other photographer in history.

Although he accompanied Obama on trips around the world, often Souza's most memorable images were those snapped spontaneously — like this one in the hallways of the Eisenhower Executive Office Building, when Obama fist-bumped custodian Lawrence Lipscomb. The images, when released to the media, helped to create a narrative about Obama as a president who is also a friend-of-the-people.

The @PeteSouza Instagram was opened January 20, 2017 — Trump's inauguration and Obama's last day in office. After posting two seemingly innocuous photos, Souza made his opinions known with a third picture. That image, posted January 22, shows the former president in the Oval Office, with red curtains in the backdrop, as here. The shot was a jab at Trump's dissatisfaction with White House decor.

"Shade" is not Souza's first book of images from his time with Obama. In 2008, before Obama's election, he published "The Rise of Barack Obama," which included images from his time as a senator and later on the campaign trail. In November 2017, "Obama: An Intimate Portrait" was released, featuring many images like these, which spotlighted the former president's ease with children.

Although this image was snapped by a Reuters photographer, Souza captured the same moment — a private moment between Merkel and Obama at the G7 summit meeting in Krün, Germany — with his own lens. A similar image is included in "Shade" as a means of conveying the differences in the relationship the two presidents have had with the German chancellor.

In an interview with the New Yorker, Souza said that some days it was hard to know how important the shots were that he was taking. Like this one, above, which occurred spontaneously but in retrospect, held quite a bit of meaning as an image of the importance of representation for young people.

Although Souza has risen to fame as a result of his award-winning photos and Instagram jabs, the photographer posts few selfies. Seen here on the other side of the lens, Souza's job as official White House photographer means he was present throughout the entirety of Obama's eight years in office. He claims to have only missed one day of work due to illness.
