I saw Frantz last night at local film society, digitally projected. I'd assumed wrongly it was digitally originated. Mostly black and white, Pascal Marti apparently used super-35 Double-X. The colour footage shot with Vision3 500T. What I found amazing was how the two stocks looked so similar. The inobtrusive lighting maybe had a lot to do with it, but it was incredible how the shots blended together. In fact, there were instances when a black and white shot would subtly change to colour. So this was obviously V3. Yet the preceding monochrome shots were the same. Were they V3 too ? Was Double-X used not so much ?
Incidentally the whole film had a kind of magenta cast in the darker areas, but this was perhaps to do with the digital showing.
