Years later we are still waiting for chromes and they waste (my opinion) time on black and white. These are the facts, then you can make whichever novel suits you best out of it
How difficult is to understand that for manufacturing a color film you first have to test the black and white layers of the film?
you understand it right. They have to reformulate colour reversal film from scratch, and it is my understanding that it is a lot more complicated than coating a single layer of black and white emulsion.
Source of this information? It is only your guess, not a fact.
My concern is that they will need years of research and reformulation to achive their goal. It's not just getting the recipie out of a an old book found inside the LRF, in the meantime healt&safety laws changed
Source of this information? Again, it is your guess. You are claiming, out of nowhere, that the formulas for Imation Chrome 100 will not be usable because 'health&safety laws have changed'. Yet, for example this is the same that some people said about the Kodachrome films and process -- "they can't be made because they won't comply with current health and safety standards", and Photo Engineer has proved them wrong.
Last time Ferrania made reversal film, wasn't in the 1980s or the 1970s. It was the early 2000s. I can bet the films and formulation has no problem complying current rules and regulations.
If they weren't able to comply with such regulations they would have known this from the start, before creating the Kickstarter. Corrado Balestra would have known and told them.
What the Ferrania team has said is that they will make a
re-engineered version of Imation Chrome 200. This is
not the same as "starting from scratch". The reason they need to reengineer, if i have learned correctly from all of Photo Engineer's posts, is that the film is going to be coated in a different coater than the original. Original coater = Big Boy. New coater = Modified LRC coater. And this always requires adjustments to the emulsion, etc.
It is NOT the same as starting from scratch.
Frankly, i don't understand your pessimism. I see all this chronology of events from Ferrania as a typical engineering project -- there are setbacks, but this doesn't mean we'll have to wait an eternity or that they have abandoned the idea of making an E6 film. As I said before, the setbacks were due to external factors; they have the people, the chemicals, the triacetate base rolls, the coater, the building, the spectrometers, the formulas, the patents, the packaging machines... why couldn't they make the film?
