LUCKY C200 120

It’s very slow, like EI 3, and it didn’t look particularly true to life from the one sample image I saw

There's a decent chance that they have the formula for an E-6 duplicating stock rather than a camera film (people forget how much demand there was for duplicating stocks not so long ago). My understanding is that the formulae that made it to the plant were largely those of products that were in such high demand/ price sensitive that it made sense to manufacture them closer to market.

I think that the reality as to what they can make will depend on what they have in their formula book (aka whatever got licensed to them) and can achieve without major reformulation rather than being anywhere close to fulfilling people's fantasises of various materials. The probable reality is that they have recipes to follow rather than necessarily having a set of techniques and researchers to product build at a more fundamental level. That may change relatively quickly.

@koraks, to follow up on the LF question, if the formulations are for CTA rather than PET coating, and if thick-base CTA is not readily available, there's quite a lot of work that would have to be done to potentially enable the emulsions to go on PET base.

IIRC they’re using 0.1mm PET for everything. Lucky doesn’t make polyester from my understanding, but they’ve been making PET for a long while. It shouldn’t be too hard to put film on thicker base, just a matter of getting the thick base, assuming they even bother to, they might just use 0.1mm PET and cut sheets from that.

Given that most of the alterations relate to getting the emulsion coating package to work with a PET substrate, the base thickness difference is very minor. That said, if there are no other current products that they coat that use thick PET base, then the economics might take some time to add up.

Thinking about it now, I bet they could coat on thick PET if they wanted, considering a large part of their film operation is for PCB and X-Ray film. Just a matter of if there’s enough demand for sheets to justify an entire master roll (or multiple)

I think it is a typical product decision: for now it needs to focus 100% on getting color emulsion right, 35mm and 120 mass produced, and making a decent profit. Only after that it will look into the potential demand for sheet format.

Yes, from black-and-white to color, from 135 to 120, from C200 to C400—one step at a time.
