Actually, in that particular shot, the channel misregistration is different on the models and on the background, so it was clearly part of the original compositing and in order to fix it, Mike had to cut everything out of it’s background and shift each element separately, thus literally re-compositing the shot.

Any chance you can point me to what shot you’re referencing? I’m watching the legacy videos on Vimeo looking for it.

Edit: I believe I found it. Is it the shot of the X-wings on top of the Death Star? The original version has a stain in the top left corner that he fixes.
