If you mean the shot of R2 in the canyon, I didn't know they "fixed" that in the SEs.
They didn't, and it's in no need of fixing either as it is part of the original photography, it's the way it was filmed, it's supposed to give you an unsettling feeling, it's sort of a point of view shot from the Jawas ala slasher films. But it is also shot that way so that we experience it from Artoo's point of view as well when the rocks are falling from the cliff etc. It's simple but brilliantly shot.
