Syncing the negative1 version to the GOUT and color correcting it to match Harmy’s reference material would produce a nice copy of the film. As it stands the colors on the negative1 version seem initial. (Their color correction removed most of the red tint, but it ultimately doesn’t look very great).
The Eastman and IBtech colors are two different beasts. I don’t think this release should be made to look like a Tech, as nice as the color is on those prints.
I think this release could use a few tweaks in some of the low-lighting interior scenes, but overall it looks great considering how difficult it is to correct something like this.
