If you already know, in 1995 for the Star Wars special edition released in 1997, Pacific titles restored the film, cleaning it in a 104 degree sulfur bath which helped to remove dirt, dust, and any residue impregnated to the tape, then hand rubbed, the negative had never looked so clean and new, the only bad thing was the color fading, luckily George had copies of those films made in technicolor that had a slower color fading than the Kodak film, thanks to that they had the base to restore the colors, first they scanned the original negative with a professional scanner at the maximum resolution of that time, 2K, they also scanned the copies for the colors, the negatives had to be cut in the scenes where there are transitions to redo them digitally, they added the new CGI scenes and they printed everything on a new fine grain tape so they didn’t generate too much grain, now my questions are: If in 2004 Lowry scanned the special edition negative, which caused them to spend months working on grain reduction and sharpening contours unnecessarily, why didn’t they just use the digital master that pacific titles made for lucas film ? why if Lowry scanned the new physical master, it will have worse quality than the digital master, and the second question is: Lucas film in 2012 restored Star Wars to 4k according to media and leaks and we didn’t see any of this until Disney released the UHD version in 2019-2020, my new question is, where does this edition come from and what base does it use ? I have heard out there that this UHD version is a scan of the 97 physical edition, The problem is that it is not UHD, it is 2K, even if the negative was scanned to UHD, (3.8K or 4K) this will still be 2K, and of a quality quite inferior to Pacific’s digital master, except that Lucasfilm scan the original '77, '80, and '83 negative to UHD and on top of that put the changes in CGI in 2K, which still gives me as a third question: Does that CGI in 2K come from the physical master or the digital master, I know it’s a tedious field and there are many questions but I can’t get them out of my head for days now.
