I did this small tutorial a few years back and thought it would be fun to revisit it. Here is the link - OOTBWorkflow: Chiaroscuro mini-tutorial
This tutorial is also in the workflow sticky thread at the top of the forum page.
P.S. - the gosling image is taken straight from the camera








I was really only including it to show the concept, but I agree with your assessment. I thought the image looked a lot like some of the paintings that used this technique, sometimes this era of art history is called the dark ages.
