Today in Parsons, Kansas the last rolls of Kodachrome ever to be processed will run through the processor at Dwayne's photo. The store is selling T-shirts which sum it up pretty well:
"Kodachrome:"
"Paul sang about it" (a reference to the Paul Simon song "Kodachrome")
"A state park was named after it "(in Utah, in case you wondered)
"National Geographic shot their most famous photos on it" (Steve McCurry's portrait of an Afghan girl, among others)
"and we developed the last role"
The New York Times has the full story here.
The New York Times Lens blog features a slideshow of Kodachrome images today. Including photos from the last roll of Kodachrome ever produced - shot by Steve McCurry.
