(cool. People are discussing motion pictures and ICC in the same place)

Up until now, it seems that the film industry has been soundly ignoring ICC CMS and has instead implemented many proprietary methods for performing color adjustments on film images. This is in spite of the fact that color adjustments (a.k.a "grading") are done for every film and it plays a significant role in the production of each movie. The necessary color adjustments may be different for a different reel of film, different scene., etc.
I would say the reason is it hasn't worked very well in the past (for motion pictures). ICC is/was hampered in a couple of areas with respect to using it for motion picture. Just for an example, how about under range? No one has mentioned that in this thread. We often have values "less than zero" It just wasn't ICC's job to deal with that.
Other reasons have included tools, I can't get my 4 perf 35mm to stay flat on my Gretag SpectroScan, rats!
These things are all changing though. When it works, people will use it. And by the way: On May 22, 2005, at 1:38 PM, Bob Friesenhahn wrote:
Kodak Cineon recommends a warmer color temperature of 5400K. See the white paper at http://www.filmlight.ltd.uk/documents/FL-TN-00-002.pdf for a table which lists the various color temperature standards.
This is a funny subject. 5400K is *really* red. I have access to a few film projectors. Admittedly they are not quite like the ones in a cineplex but their light is *no where* near this red. Sticking to the wonky color temperature numbers (my projector is like a black body radiator, what?) the ones I have access to are more around 6000-6300. So then, anybody know why this is "recommended"?
