Technology moves on, a scan from 2004/2005 is not the same as a scan from today, they can apply sharpening at the scanner, so it does make a huge difference, some older scans would certainly benefit from being redone.Mark-P said:A 4K scan is a 4K scan. It's the processing done after the scan that makes all the difference. I mean really, the whole point of a 4K scan in the first place is for preservation. Once you have a 4K scan there should never be a need to do another one - you can always go back to that scan and start from scratch to make a new transfer.
Those Bond films went through the Lowry process, i think some of them look like crap, yes this was processing done after the scan but do they even have the original scanned files, if so then maybe they would work.
There are people who work in the industry that believe you need a 6K scan to capture all the detail in a 35mm frame so i believe for preservation purposes they will redo some of those 4K scans in the future.
It's also worth bearing in mind that storing digitally is less safe than storing on film, doing a 4K or higher scan and then outputting to film is better for preservation purposes, digital needs redoing and is not as safe as many might think.
