A Wratten 85 filter is a warming filter for shooting tungsten balanced film in daylight -- makes things orange.
Exactly the opposite what you said in your other posts.
As I mentioned before, 80c is the corresponding cooling filter.



Also, I looked up "Pola-Screen" and it was an Eastman Kodak patent in the 1930's, not Polaroid as you said (while citing a manual).

Memories are funny things, aren't they?
My first full-time job after college was as a QC tech at a Technicolor film lab, and I stayed in the the commercial end of things for over fifteen years while supporting my habit as a musician. Much of my technical education came straight from Rochester. And yet I still get things wrong, too. With that in mind, adieu.

Check out Edwin Land on Wikipedia. By removing/dropping the 85 filter, you go to a 3200 K tungsten balance. Ektachrome Commercial was a tungsten balanced film.
