I must admit I have always regarded pulling colour film as a Very Bad Thing, because
of the crossed curves. I know studio guys who do it, to about -1stop max (more
usually -2/3 or -1/3, differences I can barely see), but as you say they use CC
filters to mitigate the effects. I shoot nearly all 35mm, and CC's really don't fit
well with that.

Yes! I've seen the sort of results possible and agree, digital already surpasses film
in many respects (oh, the contrast range after tranny:). It's a shame that sort of
quality is presently limited to MF/sheet cameras and costs as much as an upmarket car.
