What filter should I use to remove green cast?

[stradibarrius]

When I shoot film inside under my studio lights or in m shop I get a green cast. With digital I can adjust the White Balance and select the correct temperature which is 2850K.

what color correction filter should I use to remove the green cast I get with film?

magenta ?

Use incandesent lights and not flourescent lights.

For your purpose 80A probably won't get you the right temperature. IIRC Hoya makes the FL-W and FL-DAY filters for this purpose, which are magenta.

30 magenta is the universal for fluorescent lights. Some films require 40 magenta.

The color shift has nothing to do with color temperature.

Fluorescents usually need 30M to correct the green cast as Walter says, and then they may need additional filtration to correct color temperature. So if you're setting your digigizmo to 2850K, you're probably filtering White or Warm White fluorescent tubes that are designed to balance like tungsten, and you could use 30M + an 80A filter or an FLW filter, which combines magenta and blue to correct warm fluorescent bulbs to daylight film. FLD is for balancing daylight fluorescent bulbs to daylight film.

Kodak used to publish a guide with specific correction factors for use with a range of fluorescent bulbs that could be used in lieu of a three-color meter.

Keep in mind that the discriminating digitographer may wish to use filtration even with a digital sensor. When you adjust camera white balance, the color filters on the Bayer sensor aren't changed, the change is made in software. Using white balance controls throws out some dynamic range.

"Digiographer" that's a new one on me, is it a photographer with his brains removed ?

Your assessment is correct although I believe the technical term is "digi-snapper" as opposed to "film-photographers-who-know-what-they-are-doing-and-shoot-digital-to-satisfy-the-customers'-demands".
