Hi Everyone,

I've been charged with the task of correcting 3500k fluorescent light for tungsten balanced film. My questions are:

1. Is the difference in color temperature enough that I need to gel it to balance it?

and

2. What minusgreen filter would I use to correct the green, if I need it at all?

Thanks for any help!

You just have to test it. The amount of green and actual color temperature can vary between manufacturers. You can use a digital still camera to do your tests.

Start with the lightest density of minusgreen (1/8th) and build your way up until you've neutralized the green. Then do the same with CTO.
