I've visualized this type of shot for a while but haven't been able to capture it until now. The idea was to show just a sliver of sunlight on a subject while everything else remained in deep shadow. To accentuate this, I underexposed the areas in the shade, rendering it near black. I then converted the shot to B&W in Lightroom and added a bit of contrast.
