KA: Kodachrome "just not practical to try to replicate in today's market."

[E. von Hoegh]

Sal, the first re-exposure of Kodachrome is through the base - after removal of the rem-jet.

I'll bet no one knows where the barn is!

rem-jet would be applied to side of the black Estar "backing paper" that would be in contact with the rear of 120 film base. There would be no rem-jet on the actual film to remove before re-exposure.

BUT the presence of the rem jet disrupts internal reflections inside the film base. it is is a few wave lengths away it will not have the desired effect. It one were designing a totaly new Kodachrome like process, it is POSSIBLE that a AHU layer might be invented, that would clear in a pre-bath or during first development without messing up all the rest of the sensitising dyes, which have to stay in place and working so the re-exposure will be done to the correct layer.

What is the name for that three-color-separation camera where light from the lens is directed through prisms to simultaneously expose three glass plates through individual color filters?

Afterwards, the images on the plates are sequentially exposed again through filters to form a color image.

It's not Kodachrome, but it's cool.

that is basically how three strip Technicolor worked. although two of the films were in bi-pack arrangement and were colour sensitised. three B&W records were made and used to create the colour dye matrices, (like dye transfer prints)

Yes, Ron, I know. Look again at my fantasy post #398. In it, I specified that rem-jet would be applied to side of the black Estar "backing paper" that would be in contact with the rear of 120 film base. There would be no rem-jet on the actual film to remove before re-exposure.

Getting one's head around such science fiction might understandably be a challenge for someone so experienced in the real world of Kodachrome.

If it is black backing paper, then rem-jet is not needed.

But then, Kodachrome is gone.

OK, substitute any kind of coating you like for rem-jet. I picked that out of the air as a hair-brained way to make black Estar "backing paper" non-reflective.

If it is black backing paper, then rem-jet is not needed...

Note that I put "backing paper" in quotes, since it's not paper at all, but black Estar.

...But then, Kodachrome is gone...

As is the common sense of those who argue for its return with a straight face. My post #398 was an intentionally absurd proposal to poke fun at what a government-run, "moon shot" type Kodachrome revival project might pursue.

You guys are too serious in a comedic thread like this one.

The Fiat Tipo S76 has a four cylinder SOHC engine with twelve valves, triple(!) ignition, pressure lubrication, bore & stroke 170mm x 250mm. The car has final drive by chain and is geared for 128 mph @ 1000 rpm and produces 300 hp at an unspecified rpm.

Let's get Fiat to put it back in production!! It's way more feasible than Kodachrome

Look at how many views here and how many actual posts. See how important Kodachrome is?

PE just out of curiosity : If EK would offer you one day in the future 10 rolls of "New Kodachrome (type IV) " would you then use it (as a present) or would you realy say :"I can't shot with this stuff I might give it away" ?
IF (and that seams to be the problem) you easily can give it to Kodak and they will develope it?
So you would not have any stress with complications due to your experience with Kodachrome procedures at EK you remember?
with regards
PS : Hope this question will make you not such stress I mentioned above.......

But there is a serious point here:
120 is still around and Kodak had a pesky issues with this paper backing of the format, being as well a quite specific material. I wondered if plastic (opaque estar as here) could be a very fine substitute. Guess it would mean retooling part of the finishing line as well...

Saw somewhere that Ektachrome may be delayed another quarter. What about bringing it back?

Fuji's well on its way to abandoning E-6, probably all film. Reviving Ektachrome makes at least some sense in that context. It's possible to discuss the wisdom of doing so, but at least the project is slightly rational. Kodachrome -- would be suicidal for Eastman Kodak. A corporate re-run of George Eastman's "my work is done, why wait?" note.

I currently shoot only negative films. No reversal at all unless it is an E6 film in a negative process for example.

But shooting is hard to do when chained.

I had an interesting afternoon with Mark and Nick and we talked about some of this.

Perhaps Kodak's already moving ahead with suicide.

I keep tabs on the prices of certain films at B&H. Yesterday, and for quite some time before that, 10 sheets of 8x10 320TXP was $74.95. Today it's $119.95:

https://www.bhphotovideo.com/c/produ...x10_Tri_X.html​

I contacted Henry Posner to ask whether the 60% increase was an error or resulted from Kodak Alaris raising the wholesale cost. Henry just answered: not an error. Alaris almost doubled its price, retroactive to April 1.

Methinks Kodak is exhibiting a level of desperation so great that it has shot itself in the foot. Also, the 100 sheets of 8x10 320TXP in my freezer will be the last I purchase.

I have to have access to get information from ex-Kodak engineers.

What happened to Dwayne's Kodachrome processing equipment? Was it bought by a shell corporation working with the Chinese government?
