And I have to respectfully disagree about the extensive color timing done for Jackson's LotR. He got the colors he wanted that were simply not available in the actual photography, no matter how true to color it may have been. The example that comes most quickly to mind is the lush green of Hobbiton, which was simply not there during original photography.

So, with the tech toolbox now available, what's a filmmaker to do? Leave the drab green that 35mm film captured perfectly? Or render the color timing to result in beautiful green for the fantasy film?
