Yeah, I figure that for color grading purposes there will be power windows, but I was under the impression that these are beyond even color grading and directly change the brightness and contrast of certain areas to make certain parts of the image ‘pop’ more for 3D.
This is more of what my concern was. One of None’s difference examples shows a mid-shot exposure change on Luke to remove a shadow that he walks out from under. That’s a fundamental change to the photography and on-set lighting. I don’t think that sort of thing belongs in a theatrical restoration official or not, especially since if an official restoration of Star Wars was made on the level of other classic films, such changes to the image wouldn’t have been made, at least not as egregious as that example. It would make sense if this was done to assist in the creation of the 3D version.
But those are just my thoughts.
