Every time I ask a stranger if I can take his picture, the first response isn't "Yes" or "No" or "Why?" It's always "Me?" I think that's kind of funny. I wonder if, when this guy got home after work, he said to his wife, "The weirdest thing happened to me today..."
Technical info: Shot with a Nikon D40 and Nikkor 50mm f/1.4G lens, in manual exposure mode. Aperture f/1.4, shutter 1/1600 sec, ISO 200. Post-processing in Aperture 3: crop; recovery; several curves layers to darken the man and the bright parts of the ground; levels to darken shadows and brighten midtones; burned over the man and ground.
Thoughts for improvement: As always, I need to do more work to get the exposure right in-camera.
