Just a note about the vignetting here (this is from the Blu-ray release, with all the errors that entails) – it is not identical in all the original picture’s R-G-B layers. The above pictures have changed colors (or from bad color correction that just came through stronger) in the dark areas that were uniformly brightened.
Keeping that in mind, I made another test correction at, this time in the moon base conference room (nice, big light panels on the walls to easily check values all across the frame) . .
A dodge mask was applied to each R-G-B layer independently (instead of universally as previously tried). I worked up a spherical mask to better approximate the lens-distorted vignetting . .
. . and stretched it to fit the picture frame . .
Each dodge also was independently adjusted via histogram, for proportion of change of the vignette area, . .
. . and transparency setting, for strength of application. Adjustments were guided by an eyedropper to ensure that R-G-B color proportions remain equivalent across brightness-changed areas (like in those light panels). The result looks the best so far! Check out those brighter and uniform color, frame edges:

Just an aside …
Ever notice that in this meticulously crafted shot, only one edge (the far center light panel’s top edge) that is straight? Every other edge in the room is crooked! Was that deliberate? You better believe it! Then why? Well, where else would you expect a government agency, which conspires and lies to keep the public it serves in the dark, to meet? In a crooked room, of course.
