This film (400 & 800) both seem to have very similar characteristics to 400d & 800t.
It's strange that years were spent in R&D and coming up with such similar tones.
Also made in France? Not sure about that, I can't think of to many film producers there.
Maybe made in Rochester NY and re-rolled in France.
Of course I maybe wrong about it being Kodak Vision 3 with the remjet removed.
With so many "new" films coming to the market, it's so hard to tell, if only manufacturers told us where it came from.
