Now that it is 2011, Kodachrome processing is no longer available. The last processing lab, Dwayne’s Photo in Kansas, has processed its last roll. See For Kodachrome Fans, Road Ends at Photo Lab in Kansas and The Last Roll of Kodachrome Film Ever Will Be Developed Today for more details.
Personally, I used a lot of Kodachrome before digital, including Kodachrome 120. I still like looking at these photos; however, I haven’t used a roll of film in the last eight years.
Now the only question is how long other slide and negative films will remain available. I am voting for 2013 for the end of consumer color negative film.
