I'm aware of his work, I do think it's a little sad that he seems to have abandoned it shortly after showing it could be done. I can understand though, it's not simple.

Cyan is 1-NAPHTHOL,
Yellow is P-CHLOROACETOACETANILIDE,
Magenta is P-NITROPHENYLACETRONITRILE.

I disolve about .5mg in about 2cc of acetone. That can be mixed into 250ml of C-41 dev to make 1 shot developers(The couplers break down quickly so the dev doesn't last more than a few hours tops).

Sir if you need to develop 10 rolls of Kodachrome, how much we need to spend.

They bring back Ektachrome and that's enough for me. I don't need Kodachrome. After the discontinued Kodachrome I shot a few roll of Ektachrome instead and liked it a lot.

These couplers are all from an old book by Steigman et. al. Do not expect good image stability.

Yes, they absolutely are I found them reading old manuals on color process. At this point I'm just happy to get to play with Kodachrome. I didn't shoot it when I had the chance, and it's fun to experiment.

Well, it costs about $100 to get the needed supplies, the amounts of couplers you get is enough for a LOT of rolls, but the C-41 kit gets used up pretty quickly due to the developers going bad quickly. If you were developing them all at the same time, you could get quite a few rolls out of that before you had to buy another C-41 kit.

Ektachrome is good stuff. I'm excited to see it coming back! I enjoy playing with film process, and first and foremost I wanted to see if I could do it.

Ektachrome gives skies the color we remember.

Regarding getting the new Ektachrome developed, many, if not most of your commercial labs that do E-6 are using Fuji's 6-step Hunt Pro-6 process. If this is as good as Fuji's old CR-56 process, then it will provide stability almost rivaling that of Kodachrome. I say this based on my own experiences. I shot Fujichrome exclusively when I visited Japan 34 years ago and I had the slides developed while I was over there. So I'm sure the CR-56 process was used. Anyway, the color in those slides is as correct and saturated now as it was when I got them back from processing. I projected the slides only once and I've kept them in a variety of sleeves and environments since then. For years, I kept them in non-archival sleeves, stored in a file cabinet in my garage (I live in Houston and it gets hot here in the summer). It was only about eight years ago that I came to my senses, brought my slides indoors into a stable climate and mounted them in archival sleeves. So I guess I'm really a bit surprised that they survived my idiocy with no apparent harm done.

Anyway, I'm looking forward to shooting the new Ektachrome and I'm hoping that it will have the archival properties of the old Fujichrome I'm already familiar with. I really miss Elite Chrome 100. That was some really good stuff. Super saturated colors, especially the blues, and extremely fine grain.

Hey guys, I know this thread is a bit old but someone mentioned that it was here. I'm the person who was mentioned earlier who has developed Kodachrome.

Welcome to Apug!

It is great to have another tinkerer in our group.

Wow, this is some excellent work sir! I'm highly impressed and now I'm motivated to do this on my own, though I don't know where I'd start

Regarding this, if we got enough exposed rolls together as a community so you would get the most out of the developers, how much would we have to pay you to make it worth your while? $500? $1000? Name your price.

Thats an interesting thought, It'd depend a lot on how many rolls it actually was. And how OK people were with results that might not be perfect. 90% of the time I get great results from my process, but Its still not 100% ideal. And like PE pointed out, its likely not going to be long term stable as these arn't the correct couplers for Kodachrome. But that being said, I'm open to the idea.

You could start a thread with a poll to see how many people could commit to it. What do you think?

I for one don't care too much about archival stability or perfect colors. When you're suffering from Kodachrome withdrawal, anything will do

Heh, I understand that feeling. I'm just happy I can shoot it in color at all.

How many rolls would I buy? One and two three-eighths.

Honestly, it's highly unlikely. And we have Ektachrome....which I intend to support even though my means are not great.

Piratelogy,

I'm amazed that not too many people have replied here. Here we had a Kodachrome thread which became MANY, MANY pages long, and i've lost the count on how many times any APUG forumer wants Kodachrome back. There was also a LONG thread started by a gentleman who wanted to survey how many people would afford to pay him for K14 processing; people went crazy.

And now here our hero comes showing ACTUAL PROOF of being able to develop Kodachrome, and yet the waters are still calm and quiet. Surprising.

I see that there is the possiblity of people contacting you for K14-like processing (let's call it "ersatz K14") of Kodachrome films; after all, many APUGgers have lots of frozen stock of Kodachrome in their freezers, and we know that this stuff preserves well over time. So perhaps, if you set up to do this commercially, or at least for getting some money in thanks for your spare time, then YOU will be the one who really brings Kodachrome back.

At least until the very last virgin roll of Kodachrome in the world is exposed.

On the technical side, i'm curious to know how do you achieve the colored re-exposures. Is your processor a continuous processor (i.e. the film advances through the machine)? Because i can't figure out how the re-exposures would be achieved if you are using the classical "film reel+tank " method.

If someone could develop my last remaining 25' roll of double-8mm Kodachrome II movie film (ASA 25 back in 1978) and produce a viewable image, I'd pay to make it worth their time. It just has to be stable enough for me to view it and transfer it to another media (even if by projection).

Let's start the "who will pay for Kodachrome development and how many rolls" thread.

If pirateology starts a thread called "NEWS: Kodachrome processing now avaiable", i predict it will reach over 25 pages and eventually OVER 9000 posts.

I use a pair of LED flashlights, one red and one blue, I remove the film from the processing tank in the dark, expose the correct side of the film(The first exposure is through the base, second and third through the front) to the light 2-3 passes, and then put it back in the tank for the next developer. The third exposure is to room light and I just take it out of the tank and expose it with the lights on.
The actual development steps are in a Jobo rotary processor.
