Please don't tell others what they can and can't do. Their decisions about what is of value to them are not your call to make.
What if someone out there had pictures of a loved one on a roll of undeveloped Kodachrome? And that person had passed unexpectedly? And during the crisis they missed the Dwayne's deadline? It wouldn't be your place to tell them to skip a possible second chance at processing that now precious final roll because you thought they were beating a dead horse. Your agenda may not be their agenda. That often happens in life.
And why are you trying to rain on the OPs parade? He's obviously gone to great lengths to research and implement a possible recovery option for those kinds of situations. He's generously shared some of his proof-of-concept results with those on APUG. And those preliminary results were good enough that there may be as many as 8-12 rolls who owners may be willing to pay the price. And he says only 5 rolls are required for a minimum run.
More fundamentally, if the OP thinks he may see a business opportunity as a result of his speculative R&D work, who are we to tell him he's beating a dead horse? That he has no right to test the market with an eye toward possibly providing a professional Kodachrome recovery service. No right to make a return on his investment. No right to make a little money. That's not our call to make. His agenda may not be our agenda. That often happens in life.
[Edit: Read this thread beginning on page 12 at post #116. Wouldn't it have been great if Bob Carnie could have told his customer that YES! there was one place left on Earth that could still process Kodachrome into color transparencies? Would you have told his customer to stop beating the dead Kodachrome horse? That processing her late father's last roll just wasn't important enough to you?]
First of all, I'm not trying to tell anyone what they should or should not do, with their own money, they are free to spend it whatever way they like. There is a reality though, no start-up business based on requiring a product no longer manufactured, is going to live long, especially when that product is perishable and all remaining stocks are past their use before date. Those 8-12 rolls are not a done deal, they may be interested, but there is a long way between interested and willing to part with cash. Meanwhile, while we are futzing around and spending gobs of R&D and money on getting elderly Kodachrome processed, we might lose E6, because the market for it isn't exactly growing either. If I had a roll of Kodachrome at this point, I doubt I would use it knowing that it costs $250 to get it processed. If it was already exposed, it would have been processed into B&W by now, if it missed the last run.
