I've obsessed over the scene of Leia in the Tantive corridor for a long time, but it's because it's never been right to my satisfaction compared to Mike's superb example. Of course there's a reason for that, as is apparent now. The DVD and Blu-ray have crushed the gradients so much that there is now no discernible color difference between Leia's dress, the Stormtrooper armor, and the walls of the corridor. I've pulled as much blue out of her dress as I could, but I don't believe that the colors can be any more precise with this source. So here it is, as good as I can get it, and it's not going to change any more:

There will be different scenes soon, I promise. :)
