The typical filtration for Kodak films is 40cc Magenta and I think, 10cc of Red. I have used a FLD filter and slide film with good success. There may still be a very slight blue cast, but it is not too bad. Even if shooting print film, the FLD (Fluorescent Daylight) will help a lot when it comes time to scan or print. A lot of people don't realize that if you don't correct, part of the RGB is missing. You can't put back what is not there, even using Photoshop. If you don't filter, the pictures will be very green. Depending on the type of the vapour lamps, the results can be too green to correct in printing or scanning. Below are links to a shot of hockey where I used the FLD filter with the 400mm Leica lens and Provia 400F pushed to EI 1600. http://home.istar.ca/~robsteve/photography/Sports.htm The top two shots on this same page show some boxing I shot on print film without using a correcting filter. The scans have some cast in them that you cannot remove.
