I looked at what goes into making Kodachrome because I was curious and I found that it is quite a complex film both to manufacture, and to process.
I would like to propose a more viable option, why not ask Kodak to put more effort into making an E-6 process film that displays the same color range as Kodachrome. Yes, there would still be those that would reject it as nothing more than an impostor, but still there are others that would embrace it.
Kodachrome has been on life support for a long time now, and Kodak was right to pull the plug on it. The only reason we can't a better slide film from Kodak is because they have been leaning on Kodachrome like a crutch and using it as an excuse to not produce a better E-6 process film. Now that Kodachrome is gone maybe Kodak will put out something to go up against Velvia and win. I have a feeling that the chemists at Kodak would love the challenge, and now that the bean counters can't lean on Kodachrome maybe the E-6 Kodachrome project will get a green light.
Honestly if you really want Kodak to bring back Kodachrome you have to ask yourself this, when is the last time someone invited you over to see the slides of their anything? Do you own a slide projector? Do you know anyone that is shooting slides, not just Kodachrome, but any kind of slides? If you know someone that shoots slides, do they own a slide projector, and are they using it?
I love my slides, I love my slide projector, I love my stereo camera that I use to shoot stereo (3D) slides, I love my slide viewers and I bore my family and friends at least once a week with slides.
Last week I shot 4 rolls of E-6 slide film, and my three year old daughter shot one, I also finished off a roll of Kodachrome. I processed and mounted two rolls of stereo slides at home, sent three rolls of E-6 out to Fuji via the Right-Aid downtown, and the Kodachrome went to Dwain's via USPS, I have the stereo slides I did at home in hand at about $4.00 a roll for process and mount supplies, I will get the E-6 back from Fuji next week (probably late because of the holiday) at $6.27 a roll, but it will probably take until the second week of December or longer for Dwain's to deliver at $14.50 a roll plus postage to Kansas. Kodachrome is just a pain to deal with, it's expensive, it takes longer than it should, and the word Monopoly comes to mind, even though they are probably breaking even on the process.
Yes Kodachrome is great stuff, yes you can't beat the color range, but honestly I believe that if it wasn't for Kodachrome we would have a better E-6 film from Kodak today and wouldn't have to wait at least another 3 years for it to show up if it does at all.
I will be shooting my last roll of Kodachrome after the Christmas tree goes up, and it will be expressed to Dwain's on December 27th, and I might be a little emotional about it, but that will be the end of it for me.
Pick your battles, and ask for a better E-6 film, and then shoot it, that battle can be won.
