I have come to the conclusion that doing a global color correction to the JSC version of ANH is hopeless. I think it comes from a different color timed print. Since I have to align it and the GOUT anyway for my restoration project, I'll just do a scene by scene match as I go. That is a lot of work, but I can't do without it. It will mostly cancel out the DNR in the GOUT and should yield a superior master.
In the meantime, I suppose I should finish my color correction draft of the bluray.
