Which no-one in their right mind should be doing as a precorrection for VFX 
plates; if the shot's going to a compositor, they're the ones with the schmancy 
rotosplines who should be doing the heavy lifting. Do you have a standard 
pattern you've been using which can be shared? Besides LUT on ramps, you could 
show log/lin, decimation damage, RGB-YUV, compression hits, etc.

We like things to arrive from the scanner as straight-up Cineon 
(old-fashioned, I guess, though we're liking EXR), and we'll do a round of correction from 
there that's part of the VFX project, not baked into the files.

I don't see how you're going to be able to separate out windows unless one 
can save the splines into the file as a masked object. I predict you're going to 
end up with.... PDF!

Looking forward to CC'ing in CMYK :-)

PS cleaning lady arrived with keys to everything, and we tracked to leak down 
to the upstairs bathroom and turned off the toilet inlet valve. Whew!
