Photographer Uses Civil War Era Technique in Afghanistan

In the age of digital cameras, it's not all that common to see photographers use laborious techniques to capture photos. Especially not in war zones.

He used a civil-war-era technique to create portraits of his fellow comrades in Afghanistan. The results are stunning.

Anchor Carol Hills speaks with him about his motivation and experience.
