Images from Mary Ellen Mark's "Prom"
Clip | 2m 11s
All of the photographs in "Prom" were taken with a 20-by-24-inch Polaroid Land Camera, which weighs about 200 pounds and stands six feet tall. Operating it requires very specific skills, and only five of these cameras exist. The large-format prints have no actual negative. Take a closer look at some of the beautiful images.
