It takes two to tango, but one shot is what it takes to capture the essence of it.

The photo is part of a feature for the March 2012 issue of National Geographic, and here’s Pablo’s note from the field where he interviewed a man who makes tango shoes:

One of my best interviews was with Alberto Corona, a man who makes tango shoes. I wasn’t expecting the depth of passion he brought to this. It was his life. He told me, “If you let a shoe drop to the floor, it has to fall on its feet, as it were. If it tips over, it’s not properly balanced. And then it’s very important to check it on a flat surface; you should be able to fit a pencil just below the tip, so that you can shift the weight to the metatarsal arch as you step.”

Exquisite.
