What I usually do, is that I correct the same frame on the print to this reference frame, and then correct the other frames in the scene with that color correction model, which should then yield the references for the other shots in the scene. This way the color grading for the scene will be consistent …
That’s an excellent approach! (I missed it, if previously stated.)
Just a personal taste observation: Tatooine is a desert planet (yes, the whole planet – this is sci-fi after all). It is a light-blue sky & hot during the day. It goes sunset-red to darkness & cold at night. Aqua skies would just look wrong to me. (I eye-dropper’d that last shot and noticed blue is anemic in the stormtrooper’s shadows. If blue was boosted, that might also produce a better sky – more like that on-the-set shot.)
