As 2012 comes to a close, Soledad O'Brien sits down with Jonathan Klein, co-founder and CEO of Getty Images, to take a closer look at the best photographs of 2012.
"You don't need the explosions, you don't need the guns and you can get that message across," Klein says, explaining that some of the most powerful stills are not those that depict violence, but rather those that show a personal moment.
"People always say, "what's an iconic photo?" And an iconic photo is something that absolutely captures the moment," he adds. "When we think back to major events during our lives, either events of a human scale with family, close human scale or those big historic events, it tends to be a picture in our minds and there's something about that photo, which makes it iconic. You can break it down technically, you can say it's the composition or the lighting, but it's what it makes you feel."
