Very, very rough test for an idea regarding Luke dropping the lightsaber:
Just a thought. The lightsaber right before Luke drops it is a bit low in the frame, given the action we are about to follow of it falling out of frame. I wonder how this might look zoomed in slightly and bringing the saber closer to center of the frame. Perhaps someone with the 4K copy could provide this single shot if this proves to be an improvement.
EDIT: I lied. Of course it’s not “just a thought.” I want it to be good so that I might use it myself. 😉
