Just to prove a point: The first two couples of pictures are examples of digital restauration (looking pretty much the same but without dirt and excessive dupe grain and fading - it's not a perfect example becuase the 2004 "restauration" wasn't very good but it should give you the idea) and the other three are examples of digital recompositing (looking substantially different, missaligned and being in no way representative of what was achived at the time the films were created).
