For photographers: The blue in the background here was really bright, lit by full sunlight. He was in shade, but the bright blue tent top and concrete behind him threatened to ruin the shot. You can only compensate so much in camera, and some candid situations you just have to accept as they are.... So the shot was saved in part by the use of Color Efex Pro software, specifically the darken/lighten center feature, which really helps some portraits.
