This is what the doorframe around the Tantive door looks like just before it blows
(thanks to MV for the image)If you scan at 3K, it is just a blur, at 4K you can see the pattern and at 6K the pattern is clear.
This is from a 1977 print, it will be interesting to see if the SE print has this level of detail or not.
The negative would have far more detail again.
This is actually not the case. I have a 2k copy (2048x858) of a 35mm scan, which shows the pattern fairly clearly.
