In a perfect world this of course should always be standard practice.

What about mixed lighting where you have no choice?

Can anyone rif on 4th layer technologies (fuji) and whatever Kodak does to help in these situations?

I've noticed with tungsten illumination shot on daylight balanced negative stock that newer films handle this MUCH better than in the past? ? ?
