German photographer Bettina von Zwehl took this photo series of one-year-old babies at an instant of total (rare) concentration. Aren’t they gorgeous? Von Zwehl used toys, dvds and eye contact to get the little guys to stay still. “They sat on a table, looking at me, and I took the picture with a long cable release,” she says. Since many of the babes were still too wriggly to photograph, it took more than a year to get six final portraits. And the goal of the project? “I was hoping to present each baby as an intelligent human being,” she says.

P.S. Baby mouths are so adorable.
