May want to composite the shot with a black solid color plate. If the lighting on the black doesn’t matter, that’s the easiest… but it may look a bit weird… You can test it by downloading some green screen footage of a person and matting it out and then combining it with a black plate.
Of course, not Roger but I’ve been following these forums for a while now and feel like he generally answers these questions with a no… that he prefers bouncing (without sandwiching) and finding the right angle/time of day. I think on some shots a smaller low-level diffusion to keep the directionality with perhaps lightly softening the quality of light… But I’m following to see what others say as well.
This is such a good example of masterful cinematography. Less is more … way more often than less is less… a small fix to make the perfect light.
