The screenshot of Luke and Beru looks absolutely right, better than anything I have yet accomplished, colorwise. I would be interested in seeing these same color settings used on other scenes. You say that color correction is per scene, however it's my experience with ANH that practically the entire movie suffers from the same damaged highlights and oversaturated blues, suggesting that a single correction would go a long way to solving these problems, and only minor scene by scene color correction would be necessary to make each scene exact. In any case, incredible work!
What tools do you use for the color correction, if you don't mind me asking?
