In 1984, photojournalist Steve McCurry was in an Afghan refugee camp in Pakistan. He followed the sound of voices to a tent where he found a group of girls. "I noticed this one little girl off to the side that had his incredible set of eyes that seemed almost haunted — or very piercing," he tells NPR's Audie Cornish.

McCurry snapped a picture that ended up on the cover of National Geographic's June 1985 issue. "The Afghan Girl" became one of the magazine's most widely recognized photographs — and one of the century's most iconic. To get that shot, McCurry used a type of film that has become iconic in its own right: Kodachrome.

The film, known for its rich saturation and archival durability of its slides, was discontinued last year to the dismay of photographers worldwide. But Kodak gave the last roll ever produced to McCurry. He has just processed that coveted roll at Dwayne's Photo Service in Parsons, Kan. — the last remaining location that processes the once-popular slide film.
