I wasn't familiar with chiaroscuro lighting, looked it up and found it's also called Rembrandt lighting. It's a beautiful, dramatic effect. Was that technique used with your avatar photo?

I used chiaroscuro lighting, in other words, to reverse the brightness of the sides of the mask with the brightness of the background. :-)
