Dealing with Sodium
At the moment I'm DPing a film which includes a huge night scene exterior on a terrace that's sounded by sodium vapour lamps. They are incredibly powerful and outshine the bar's tungsten sources.
The problem is correcting the unacceptable sodium spectrum and bringing the level down to act as a fill on our subjects while simultaneously lighting the background with that classic urban look.
Luckily I can pretty much do what ever I want in terms of lighting including turning off the sodium street lights.
I'm considering doing just that and then rigging 2kw tungsten floods with a 650 Sodium gel or 1/2 CTO (and maybe a bit of plus green) to mimic the sodium but keep the integrity of the skin tones in the shadows.
Then the key becomes a mix of candle and tungsten from the bar, most lightly with practicals and kinos on our subjects.
I'm very open to any solution and would love advice on mixing, correcting and dealing with sodium and tungsten.
Thanks so much in advance.
