I rarely mean to make a serious face for the camera, but my photo-smile is a little strange. The thing I'm staring through is called, I kid you not, a cucoloris. It's usually used to cast shadows, but is also interesting to look at by itself. Or through, as in this case.
There's a hard light to camera left, behind the cucoloris, and a gold reflector to camera right, filling in that side of my face. I later decided to crop that side of my face (and my other eye) out anyway, but you can see some of the fill on the (subject) left side of my lip and beard. I underexposed by almost 2 stops in order to drop the charcoalish gray board to black and tone down the highlight on my cheekbone.
