A small Kansas photo lab is the last to be processing Kodachrome, and their last roll will be processed today. Here's a paragraph from a NY Times article yesterday:
At the peak, there were about 25 labs worldwide that processed Kodachrome, but the last Kodak-run facility in the United States closed several years ago, then the one in Japan and then the one in Switzerland. Since then, all that was left has been Dwayne’s Photo. Last year, Kodak stopped producing the chemicals needed to develop the film, providing the business with enough to continue processing through the end of 2010. And last week, right on schedule, the lab opened up the last canister of blue dye.
This was my favorite photo in the NY Times Article:
