Hello Gents,

I have a rather odd question: Is there any frequency or frequencies of visable light that cannot be recorded by Kodak Vision or Vision 2 negative stocks. If not, is there any combination of lens filters/light frequencies that would result in a visable light that won't record to those stocks?

There's a yellow arond 560 or58o which falls between the red and green layers which the film stock is relatively insensitve to.
This was exploited in the sodium vapor travelling matte process. Since it was prior to the internet, you'll find little information on the web/
