Me yelling. Lit by a huge flashlight, covered in a guitar cleaning cloth. That is the extent of my lighting equipment.
Taken in a dark room, the flashlight was on a chair and my camera was propped up on the floor pointing towards me. My face is about a foot from the ground. I just raised contrast and some stuff in RAW to get the picture dark enough so the background wasn't visible.
Used it in a challenge on DPC, www.dpchallenge.com/image.php?IMAGE_ID=841281
