But the post really had nothing whatsoever to do with chemistry, or film-making...
Both Foma and Ilford have made colour materials in the past. Foma's were probably based on the old Per-war Agfa formulas. They can't dust off those old formulas as they are not for the current popular process of E-6 and or C-41 (or ECN2 and ECP2).
There have been rumours out of China on APUG that someone by the name of SUNNY has set up to produce a colour product based on the old Ferania/Dynacolor/3M/Imation/Ferania products. This rumour is vague enough that it might (or might not) include actual machinery and technology.
Foma has been using Film Cassettes that are identical to what ferania was using at the close, so it is likely that they have bought at least Some items from the ferania Close out sale.
Anyone who used Ferania Film will of course remember that while it was "Good" it was not "Great". Anyone who is still using film is probably looking for GREAT.
Another shade on this topic is that the Kodak film Marketing business is now owned by the Kodak Limited pension Plan. I would be surprised if someone has not been working on a spreadsheet on the economics of buying or leasing Harrow to make smaller batches of Film than is economical at Building 38. That sort of plan may have one of the remaining makers contracting to do the conversion and packaging of the coated film. If the files were not already thrown away, it should only take a few months work to get at least Kodacolour back in production there.
The take away is that it probably is not worth speculating at this point. let sjust enjoy what we have.
The Harrow plant is now owned by KPP, not just a film marketing department.
Well many tiny (by Kodak or Fujifilm standards) producers were making pretty good color photo films even in the 1960s and certainly in the 1970s.
Not everyone needs a Kodak scale production model to make a happy profit.
AGFA is still making some color film. It can be developed as a negative or reversal. Ferrania certainly has the knowledge and can ramp up. Sunny or Lucky in China and maybe even ORWO or Svema could do it.
For all the stuck people that are concerned that the lower tier producers may not make color film as good as Kodak or Fuji, I say I would rather have a nice supply of Good color film than NO supply of Great color film.
But then I am exstaticaly happy with Kodak Gold and Fujicolor consumer films which I think are amazingly great films for $2 a roll.
As to small manufacturers making color, Oriental comes to mind. Back in the 80s they came out with a color paper that was compatible with Ektaprint 3 chemistry. Actually, AFAIK, it was made by Mitsubishi which also made papers and films for other Japanese companies and was allied with Konishiroku.
An Agfa style film made today would have an ISO speed of between 10 and 25, and would be quite acceptable but not great in terms of what we think of today.
