Stickers
Jason, like most kids his age, goes nuts for stickers. What I'm not sure is quite as common is the fact that as soon as he gets his hands on some, he starts sticking them all over his body. As you can see, he particularly likes to put them on his belly. And then show them to everybody.
Technical information: Shot with a Nikon D40 and Nikkor 35mm f/1.8 DX lens, in aperture priority exposure mode (matrix metering). Aperture f/2.8, shutter 1/250 (+0 EV), ISO 800. Post-processing in Aperture 3: a little bit of straightening and a curve to bring up exposure and contrast.
Thoughts for improvement: I honestly can't think of anything. I love this shot.
