New Motion Picture film: Eastman Kodak VERITA 200D Color Negative Film 5206/7206

I didn't know about that; where can I read more about this? I'd be interested.

Btw, the issue with a C41 stock cross-processed in ECN2 (which is what the Verita 200D product would be) is not only one of different dye hue. This in itself would not induce the crossover that's referred to as 'magenta highlights' (without crossover, the shadows would be equally magenta and everything would fall into place with a simple constant adjustment across the tonal range). The crossover effect is likely due to other factors, like different pH of the color developer, and different development time + temperature, which will affect the relative rate at which the different emulsion layers develop. So I'd expect that the 'other chemical factors' that you refer to are more significant here.

I think it's based on Ron's comments about the CD-3/ CD-4 mismatch.

However, my own suspicions about it 'just' being cross processed Portra relate to the MTF plot in the Verita datasheet. I don't think that simply cross processing alone would completely negate the DIR couplers' effects at low frequency as much as the Verita data suggests. The sensitometric curves are also a bit too good (and in line with ECN-2 more-or-less) for the effects of cross-process alone. I still suspect that it's a bit more hybrid (portra emulsions/ sensitising dyes and Vision3 coupler set?) than some want it to be

"Therefore, couplers in C41 films are selected to be optimum with CD4."

I'm not sure what else needs to be said.
