#PicOfTheWeek, Natural Light
Taking advantage of situations where the environment is reflecting light can be tremendously beneficial. You don't always need an external flash when there are plenty of naturally occurring lighting hotspots.
The time of day and the placement of the sun should have made this a difficult photo to evenly expose. The shadow on the face should be too dark to identify his beard or see the details of his facial features. Where normally the sun should be an issue, it reflected off the cream, metal roof and when timed right, added just the right amount of light to see into the shadows. Natural light can be great tool in the right situations.
