Starting a movie this week and since we're shooting on Panavision, DP wants to take advantage of behind the lens filters. Hell yes. 2nd assistant cut up N3/6/9, 85&85N3/6/9 and 81EF.
Now DP asking me if we can slide non Kodak wratten filters in occasionally, to compensate the overall colors, like 1/4&1/8 CTB, CTO, Straw, as well as Cyan 15 you can find on Lee Filter Book to be used on grip frames.
I've used most available Kodak wratten filters but only because those are made to be used in front or behind the lens. I can't find above shades online or at the store, rental houses, etc in NY. B&H is backordered on Cyan 15.
Would it be safe to just cut up Lee filter book and make them to be slided? Look and feel safe as long as each gels are clean.
Any thoughts? Thanks!
