The only beautiful sunset we had was right before we returned our canoes... go figure... totally clear skies while we spent 3 nights on our island campsite.
i actually view this less as a sunset shot and more as a portrait. his face give a stoic feeling even when set next to this spectacular sunset as though a long hard journey is coming to an end and the sun setting has little to do with the task at hand. i also like how it is only illuminating his face leaving the last spot of sun and his face as the only 2 points of illumination in the shot. did you grid the flash?
