I may be doing a RED feature in the summer and the whole tungsten thing concerns me, especially since I may be lighting a soundstage with hundreds of spacelights, which are tungsten.
I've been thinking that when I have a high enough light level to use a pale blue filter that either has a 1/2-stop loss (which is a 1/4 correction) or a 1-stop loss (which is a 1/2 correction) to at least shift the color temp of the image partly towards daylight.
When I can, I'll use HMI's for day interior work like on location, even if in a soundstage. But I'm sure I'll have a few tungsten-lit scenes in low light levels and have to live with a little blue channel noise.
One advantage though that I'll have on that shoot is that we want a brownish desaturated Chocolate/Sepia look, and one way to get that is to light a scene very warm and pull down the chroma in post, so it may work out to light for 3200K but open up the files as if they are 5500K shots and then take the very orange-ish image and pull down the color to get brown, so I may not have any blue channel noise problems since I'm not trying to correct-out an orange cast to a neutral balance.
