Thanks for the comments, Joel and Chuck. The one Chuck prefers is the
closest to having a "correct" white balance of both the video actress
and the live cellist. It also took the most effort to make. I thought
this was what I was going for. But when I got it "right," I found that
the two women looked too much the same. My eyes did not see the drastic
color difference between the screen and the live performer, but they saw
some difference, which this rendering eliminates. That's when I decided
to get interpretive about things.
On another forum, Nathan prefers the original settings, with the live
performer "correct" and the screen very blue. I suspect I could find
someone who would like each rendering.
