It was inevitable: It was just a matter of time before someone shot the last roll of Kodachrome film.

That honor fell to Steve McCurry, who years ago used another roll to capture his haunting, iconic image of an Afghan girl.

So, what did he do with the last 36 frames of Kodachrome?

National Geographic followed him on a six-week journey that took him from New York City to India, and then to Parsons, Kansas. (That’s where Dwayne’s Photo is located—the last lab in the world that still processes Kodachrome.)

In some ways, it’s sad to mark the end of an era. But I can hardly wait to see the results.
