Sodium vapor lights are the common night time illumination in most cities in the world, and put out a distinctive yellow light. Because they work by exciting sodium atoms, the light output is a very narrow spectrum, i.e. it's not just a question of being warmer or cooler -- there simply are no other bandwidths present. Naturally this results in anything being videotaped as appear, essentially, monochromatic (for an example, see here: http://www.travelersvideo.com/amsterdam%20at%20night.wmv)

Is there any way around this to get, if not a more accurate color rendition, at least a more interesting one? Short of bringing my own lights, which is not feasible at all, I can't think of anything that will add spectra that simply aren't there.

Nice stuff Paul.
There really isn't much you can do with limited resources other than some correction in post. (bringing a chip chart and shoot that under the light for reference can help later in post)
However............
Get yourself a rosco cinegel color correction sample set. (1 1/4" x 3")
Then you can experiment with white balance through different correction filters.
Or add it as correction filtration
I'm thinking that something in the Tough Plusgreen family and Tough WF green either added at the lens or subtracted through white balance might bring you a wee bit closer to what you are looking for.

Thanks, Bill!


Well Paul, for what it's worth, both my wife and I really
like your clip as it is. We both think that changing the
color balance (or altering it) would spoil the effect.
