I love how, in this picture, the kid is the one who noticed me, while the two adults had no idea I was there.

Technical information: Shot with a Nikon D40 and Nikkor 35mm f/1.8 DX lens, in aperture-priority exposure mode. Aperture f/1.8, shutter 1/30 sec, ISO 1600. B&W conversion, crop, curves, and some mild dodging applied in Aperture 3.

Thoughts for improvement: I wish I had been able to nail the exposure a little better to get the kid's face a little less shadowy. There's also a fair amount of detail lost in the shadows in the lower left corner, mainly from the curves adjustment I added—I made a trade-off between overall contrast and shadow detail, but I wish I didn't have to.
