> Painting out these movie mistakes as part of a restoration is wrong.
It's really not the equivalent though. I don't see anything wrong with fixing a license plate or removing a reflection or a modern-day wristwatch.
I think it depends on the primary objective of the restoration. If I’m trying to preserve history, I shouldn’t fix errors. If I’m trying to make a (by implication derivative) work that maximizes enjoyability for (new) audiences, then it’s ok to fix.
e.g. a long time ago, I once transferred vinyl recordings of an extremely amateur community musical group to CD.
After thinking long and hard, I decided to fix recording technology flaws (a bad hum) and vinyl degradation flaws (crackles, dust, etc). But I didn’t fix any of the musical performance flaws.
Bottom line: I decided to respect the history of the performance, and disrespect the history of the recording and playback technology/medium.
