I noticed that we don't seem to have a thread dedicated to this topic (if we do, please link to it, and we can merge it), and I suspect it will now become quite important, so I've retitled this thread that was originally about Kodachrome 120 for general discussion of processing Kodachrome as B&W neg and made it a sticky.

Anyone with some actual experience shooting Kodachrome as b/w neg? If my K64 didn't make it to Dwayne's in time, I might need to know!
