Just as an aside, on the subject of changes made to the color timing over the years: It's amazing that if you take the Moth3r widescreen telecine, turn up the saturation and fiddle with hue and color levels to try to counteract the odd color shift issues, that even with its lossy multi-gen picture quality, you can still get a sense of the original color structure of the film.

For example, I can see the blues and greens in the Tantive and Death Star interiors. And Luke's saber in the Falcon training sequence is blue throughout - no greenish or aqua cast in the wide shots, no parts where it looks white, it's actually BLUE. (Is it consistently blue in your source, Mike?)

*sigh* I wish someone could track down the owner of the original U-Matic master copies of that telecine. Outside of an actual print, it's probably the closest visual record of what the film actually looked like in '77.

Not really related to Mike's project, just a tangential musing...
