I did this shot of my son when he was begging me to record a podcast (yes, he's wanting to do one too. We are just "playing" with his show right now.) But he was getting a bit pouty when I wouldn't let him. And this was the shot that resulted.
Light Setup: One BIG sheet of light cotton fabric clamped to the basement ceiling to be a "curtain". One Alien Bee 800 with a bare bulb placed behind the curtain. Effectively making the curtain a HUGE softbox behind Kyle. Then a wedge of FoamCore board standing on it's end was placed in front of Kyle to camera right for frontal fill.
Settings: ISO 100, F5.6, 29mm Sigma, Canon 10D
