Look at the top corners of Luke’s canopy, there [is] … a failed attempt to address the transparency issue?
There’s another bleed-through after the rebels identify the Empire’s spy-droids.
Space is filled with the Empire’s Star Destroyer fleet, exhaust ports flair bright white. Another ship moves into view and eclipses all of them by it’s shear size. As the other ships are blocked from view, their engines flair are weakly visible through the new ship.
Is this on the original film … or is the scan pulling image from other frames (for noise reduction, or such)?
