During Nat Friedman's trip to Rio de Janeiro, Brazil in January, he visited a small slum named Rocinha. When he met the children there, he came up with a clever idea - buy all the disposable cameras he could find and give them to the children of the village and ask them to take pictures of whatever they wanted and bring back the cameras to him the next day. On his blog he describes the trip and posts the pictures he got back (scroll down).

This is an awesome idea, and it's fascinating seeing what the kids took pictures of. The great majority of them of course are of their family and friends, but it's interesting seeing how they live, and how despite the fact that some of their houses have enough exposed concrete to look like construction sites, they still live surprisingly normal lives, and have televisions and stereos and even sometimes cell phones. It reminds me a lot of some of the poorer areas of PR. There's also some surprisingly good pictures. For kids who, as he says, have probably never used a camera in their lives, some of them have a pretty good eye for composition. (via)
