Zion, thanks so much for the update (and the upload).

Minor sidetrack: In my opinion (previously stated long long ago, somewhere on this thread) the Mos Eisley shot has so much wrong with it I'm not sure what a restoration could accomplish, short of working from the camera original. It's not just color balance and grain-- the concept of the effect is flawed.

The filmmakers obviously weren't satisfied with the way the practical landspeeder photographed, and it appears that the orangey 'force-field' area is actually the vehicle's real shadow, painted out frame-by-frame. I get that they wanted to see some daylight beneath the supposedly hovering craft, but there are too many visual cues indicating its true position relative to the ground. The result is that the shadow appears cast towards us, consistent with a light source coming from the background, while every other shadow on location is cast away from us by sunlight from behind the camera. I mean sure, two suns, but still.
