So, do I read this correctly? https://www.adox.de/Photo/elementor-13690/
Does Helios really have this weird layer layout, exact opposite of a typical color film? Why does it have two filter layers? I wonder how it will look "redscaled", since example photos do look red, which would make sense if it was coated in that order by accident

It is the structure of color photographic paper
Do you have any articles as to why?
I don't think any film, in 1930s or in modern day had any issues with mottling though
you still need to make the bottom layer fast, the only difference is in what dye it produces
Hm, never noticed it in datasheets

I think Adox said somewhere that they have all the sensitisers and couplers figured out, just can't coat enough layers at a timeBut I suspect it's a lot easier to make a fast blue/yellow layer than a red/cyan one.
Interestingly, there books that mention svema duplicating films with "inverse" layer order (meaning magenta on the top) as far back as 70s. And it is benefitial for a technical film. But the "paper" layout for a film seems pointless and even harmful. I really want to see what Adox will saySome old movie print films have a similar structure, though current Kodak 2383 color print film has green sensitivity layer first. They are also designed to work also with tungsten light. No filtering interlayers either.

What does 'figured out' mean, though?
It doesn'tAnd how does the number of layers coated in a single pass relate to the layer order stack?
As @koraks said it before, it probably has to do with the current limitation of the speed they are at. ISO 1.5 is pretty borderline for general photography already. If they need to sell this film to finance further R&D starting with a film that has even three or four stops (guessing here) less sensitivity might prove to be a deal breaker. Better to sell something with "character" that something only a few will be able to use...
What I was trying to say is, if I remember correctly, Adox said that this film is the way it is due to limitations of their machine- "1 layer per color", etc.
I figured that that's what you were implying, but I don't yet understand how it would make sense. Hence my question; hopefully Mirko will come along at some point and clarify. Not that he's obliged to do so, of course.
I still don't understand why they went with monodisperse emulsions, perhaps it's "training" for 1/3 emulsions of the future Color Mission III, but then wouldn't it make more sense to still use the traditional layer order? Btw, this explanation helped me a lot with understanding how color films and multigrade papers work, so I'm very grateful to the person who wrote itHELIOS has less latitude than COLOR MISSION I because of its low speed. Any given fine grain emulsion is lacking polydispersity over a coarser grain emulsion because you do not have the larger grains inside. Exposure latitude is defined by this.
The fact that we have only three layers does not necessarily affect this. The many layers are more for color separation than overall latitude but ofcourse these things can cross when e.g. colors desturate and "fall" into brown. If you had a separate semi transparent booster layer there for a given color, it could add latitude as well.

We are still working on the filtration layers. Next samples to be expected in February.
I shot a roll in Istanbul in the spring this year. Not the greatest work of art in history ever seen by mankind, but if there´s interest I can upload an image.

Hi, do you have any updates on the current status of Helios? Additionally, are there plans to offer more Color Mission 200 for sale?
But thankfully the market is curious and makes use of them, allowing to finance further development / keeping them in market. Unfortunately making color is a huge operation.I have absolutely ZERO interest in truly weird color negative film.
