What is your method? I find I am removing in postprocessing a lot of blue and green from portraits exposed with strobe on Portra 160 4x5. EI is box speed with normal C-41 development in known Kodak Flexicolor chemistry. Subject is caucasian with head/shoulders framing. The latest instance includes three generations with the youngest age mid 20s, male and female. So mixed skin “topography” and absence/presence of makeup.

I have similar opinion/experience with Portra 400 in 120.

I’m thinking a skylight filter would reduce the magnitude of correction needed in post. Any thoughts?
