I am taking photos of an indoor area and the photos are of a yellowish piece of glass but the florecent light adn maybe the tempered glass, is creating a greenish cast to the photo. So i was wondering if i used a magenta CC10 if that would work to get rid or the green, or would red work better? also is there a way to remove the green by chaning the WB to maybe around 4000k? I figure you guys are the experts and seem to know a lot. so any help would be great.
Thanks.

Try doing a custom white balance or shoot in RAW so that you can set the color temperature on the computer.

You have several options.
1. Use the pre-programmed flourescent WB on your camera. this is probably easiest.

2. Use the above mentioned custom white balance. Probably more accurate than the preprogrammed method as different flourescent tubes have different color temps.

3. Use a cc30m or an flb on the lens. Not sure why you would do this with variable color balance.

Remember that you can't mix color temps. If you're going to use supplemental lighting you need to gel either your lights or the existing light so they all match and then correct for that in camera. IE, gel your strobes green then use the flourescent wb.

Also remember that even with the proper white balance floursescent lights do not put out an even spectrum of light so your color response will not be the same when compared to strobes or daylight.

Good luck

Take a test shot with a known reference of neutral white balance, like a WhiBal Card or a White Balance Kard or Listolyte or PhotoVison Digital Target and use those values to correct in RAW. OR use one of those tools to set a Custom White balance and shoot in JPEG.

I was looking at Magenta CC filters. i was thinking of going with the CC10 rather then the CC30, the CC30 appears to add too much magenta, but i guess it depends on the ligth temp right? Can anyone suggest a good temp reader? or sumtin, or if there is sum kind of general temp table or sumtin like that. Thanks.

Slash are you talking digital or film?

If digital, and you can go back where you were, put in a piece of white paper and re-shoot, do a white balance and apply those settings to the old image.
