I have just noticed that a shot in 'Empire of Dreams' is taken from the Original Original Trilogy transfer rather than the SE or the 2004 DVD. And it looks as if its of decent quality.
Top - Clearly the 1979/80 compositing work from an OOT transfer (seen in Empire of Dreams) Bottom - the 'cleaned up' version from the 2004 DVD
Has anyone got anymore evidence of great looking OOT transfers in the possesion of LFL?
