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.

Thanks. I'm probably an example of "Amateurs Gone Wild." My audience is
limited to my wife, my in-laws in China, whatever friends I can coerce
into watching my videos, and whatever poor soul happens to stumble onto my
website. My primary goal in doing these videos is just to create a
remembrance of our travels and, hey, that is what it looked like. ;)

May I suggest that you think about more varied framings? I liked your clip
but found that one medium shot after another was not very exciting. Think
about closeups, tele shots, extreme angles, big foreground objects, etc. to
intercut with the more useful vanilla stuff.
