I disagree, it was a photochemical restoration, while the optical wipes may have been digital, they re-comp’d other stuff optically.
It’s not a matter of debate. They were digitally composited. Go to 3:38 in this video:
I don’t want to come off as dickish, but you obviously do not know what you’re talking about.
The 97 restoration was partially photochemical and partially digital. All of the non-special effect shots were restored photochemically and the wipes were done optically. The elements for all the fx shots were all rescanned and recomposited or enhanced with CGI and then outputted to 35mm film. The OCN is now a mix of the original 77 negative (non effects shots) and 97 negative (wipes and sfx shots).
