What kind of gel could I put on a tungsten light to make it look like it is sodium vapour. I am doing an exterior scene under sodium lights and their is no room in the budget for a generator but I may be able to hook a light up to a car battery.
Thanks Mario Jackson

A Wratten 16 or 21 would give you yellow/orange. Not strictly monochromatic as sodium is, but would get you a long way towards it. Any narrower-pass filter would eat up so much of the light as to make it useless.

It's been talked about before. Michael Nash suggested Bastard Amber + 1/4 CTO. Paul Cameron uses LEE Apricot 147 + Rosco Cal color Yellow 15. Either of these are good for High Pressure Sodium.

There's plenty more in the archives.

I believe I read in American Cinematographer that Wally Pfister used Rosco 15 and 1/4 cto to emulate sodium vapor in Batman Begins. I used this on a film recently to imitate, but not to match. I think it was the June 2005 issue if you'd like to look up his comments.

Hi,

I was reading today that on Collateral Dione Beebe used Light Amber & 1/2 Plus Green (on Tungsten Lights) "Sometimes we added 1/4 or an 1/8 CTB if it was too warm"

James.

Street lights and industrial setting lighting is where a color meter pays off. Mixed tubes in flo fixtures is another place. Thanks for the gel recommendations. I'll write these down in my lighting reference book.
