Here’s a quick tip for creating a dramatic portrait: Use the sun as your backlight.
I made this capture of Dean in downtown Salt Lake City by placing the setting sun at his back and then providing subtle fill light with a reflector. It can be a bit tricky to line up your camera and subject to avoid lens flare, but when done correctly it can provide nice results. On this shot, I particularly like the glowing outline around his body.
