The other use is for exposure readings using a light meter, different thing altogether.

What I was getting at, is if I have incandescent light bulbs under the translucent sheet, and daylight coming in the windows, plus overhead lighting of a different color temperature, maybe a flash at 5500K, I don't think you can ever balance it properly. This was the first step towards mixing fluorescent with flash, although I will eventually go all flash for the portable setup.
For now I don't have color balance problems, because all the lights are the same color temperature, same Mfg. I starting experimenting with a controlled relatively inexpensive light source. I may not have made that clear? Still fluorescent isn't accurate and it's not precise, or consistent. If anyone says, flash is better, I'd have to agree.
18% gray card by the way. (and I kept writing it grey card, but my spell checker keeps correcting me, I just gave up and added it.)
Off subject but on color balance. Has anyone ever tried one of those lens caps that come with video cameras, for setting the white balance on a DSLR? Is that a dumb idea, or might it work? I'm talking about shooting natural light outdoors, not anything studio.
