Clamshell lighting is one of the simplest lighting setups for headshots and portraits. Two lights are set up to light your subject from above and from below. Both are at approximately a 45 degree angle. This gives an even light on your subject, that somehow has a glowing effect. Easy to set up, and gives consistently good results. Here I used studio lighting, but obviously it is just as easy with speedlights.
