I might consider using Ferrania E6 products if I am given a few samples to test and QC. I certainly do not rely on company or corporate spin about how good a product is. A lot of money has been wasted like that. You go to their party, they give you the cake. Then eat it and tell them about it. The world too. At the moment, there is no competition for Fujfilm's E6 emulsions and they do the job well — for now. I would be very, very surprised if there is any other company out there planning to stand tall alongside Fujifilm in anything from consistent quality to the nuance of colour palette and contrast. We'll have to sit back and watch what eventuates.
Ferrania has been around for a long time. They made a lot of the house branded color film (both negative and reversal) in the 70s though 90s, although they existed earlier. In Europe, they also distributed film under there own name. I think they were the ones who made 3M's film. Quality was considerably worse than Kodak, but price was a good deal less, too.
I use to buy the 3M film (employee discount) and it was garbage. Very green cast. Even if it was free you would not want it. Hopefully, this will be better.
Don't forget that Ferrania may be able to economically coat much lower quantities than Kodak or Fuji. We may or may not like Ferrania's products when they are released, but chances are that they will be the only game in town when they hit the market.
Trying to be the best of whatever I am, even if what I am is no good.
