The Kodachrome Revival Project

I'm not a chemist, but I did see somewhere once the chemical process for Kodachrome processing detailed-out and it did not look that intimidating (it's online or used to be). Perhaps we have a member or two who's a wet chemist and can offer a learned opinion? (After all we are talking essentially about 1930's technology)

Nope Kodachrome was changed drastically from the 1930's process through a series of refinements in the 60's and 70's. The Current process was from the late 70's as far as I know.
 
This is really useful info guys, really appreciate it.

What I have been wondering is this: Isn't the color information still "there," even when it's developed as b&w? Not visible to the human eye without the dyes, of course, but could it be retrieved electronically in some kind of advanced scanning procedure? The scanner would read each layer separately as shades of gray, but the software would know which color each layer represents and calculate the final image in color.

Wishful thinking I reckon. The digital scan will only record that black and White info. The colour is added to the slides during development 🙁
 
Oh yeah, Velvia is a gorgeous film. It's just that now I've got 23 rolls of Kodachrome and I want to see what I can with it...
I can understand that, with you having so many rolls. I have one roll myself. Perhaps if someone comes up with a way to process it in color I'll shoot it. But in all reality I think it will be too expensive to have developed. If I had that many rolls I'd sell it or trade it for different films. There are people still buying the stuff. Also I didn't mean to come across as rude or anything, I hope you have good luck with the film. It just blows my mind that until Kodak came out & said they were discontuining the film the vast majority of people couldn't have cared less about shooting Kodachrome. Not me...I already had been wearing my Kodachrome Project tee shirt! 😉
 
Why the fixation on RFF with seriously expired film and now a dead process? Having just found and trashed about 20 rolls of Tmax 400 that were casually stored, I can say (as has been said above) "Throw it out, move on and buy some fresh film!"
 
Kodachrome is an interesting process but it has had its day. Colour rendition is far superior in modern E6 films and if you really want those old Kodachrome colour casts, it's easy enough to replicate them in Photoshop with the Exposure plug-in.

My last roll of Kodachrome arrived yesterday from Dwayne's: I honestly don't think I'll miss it that much.

PS, Good luck to the people trying to revive it, but I doubt it will be commercially viable.
 
Why waste your time when there is Velvia 50. This looks better than Kodachrome. Check out this W/NW thread. If people don't buy & shoot this, it too will go away.

As much as it pains me, and I was a dedicated Kodachrome shooter myself, I have to agree with this.

I'm not a Velvia 50 fan but it strikes me a much better idea to find another alternative. Kodak's E100G (I'd recommend an 81A or if shooting it outdoors) or Elite Chrome 100 is a superb film, and it will also go the way of the dodo if too many people are trying to revive something that is now dead.

I personally have settled with Elite Chrome 100/E100G and/or Ektar instead of Kodachrome. They aren't Kodachrome but they're very good, and in E100G/Elite Chrome's case provide very nice colour.

Maybe I'm flogging a dead horse but it makes me wonder why someone with the money to spend on developing something where there are now only supplies (and small ones at that) of expired film, it would seem a much more rational response to put the Kodachrome out to pasture and invest in film you can buy fresh off the shelf today.

IN fact in many ways as much as it's sacrilege for me to say it, I'm preferring the results from Ektar and E100G anyway.

kodachrome - BW processing

kodachrome - BW processing

....
Have any of you tried processing it in black and white chemicals,
...

Hi,
As I thought £30 per roll - process C22 was OTT, I have decided to go forward myself and processed a K200 yesterday.
Here are the facts:
_presoak the film for a couple of minutes. Pour out, don't be afraid by the yellow colour of the water.
_develop with Rodinal 1+100, time was approx. 20-21 min (I am never so strict when using Rodinal 1+100), temperature was rather 21degreesC. Agitation: 15sec every minute for the first 3-4 minutes, then every 3 minutes for 15 sec. Pour out, you will see that the devt water is very dirty, very black.
_wash 3 times with water at 25-28 degreesC, following the Ilford method. The high temperature will help removing the kodachrome black layer
_Fix at 20-25degC, I used Ilford Rapid fixer 1+4.
_wash again with water at higher temp (it was 25degC in my case). Ilford method, 3 successive strong washes. I added some continuous washing, at a temp of 25degC too, for 5-10 minutes.
_optional: stabiliser bath: 2 min; I used a personal mix of formaldehyde + wetting agent. I believe that stabilises the gelatin and anyway reassured me before sponging the film, for I knew I would have to. Indeed, there is a remaining sort-of-black-carbon layer on the film, which fortunately is very easy to remove. Either using wet fingers or a very soft cotton cloth (my case). Advice: If you are looking for formaldehyde, check the bath cleaning products: I have found that the COOP basic bathroom cleaner is a solution of it, needing only a bit of dilution (£1.5 a 500ml bottle, very good!).

Results: quite contrasty, but visually fine, similar to other BW negative films I could have used (I am yet to properly scan the negs).

Let me know how it works for you.
