To be honest, I don't see much difference. :-( Pleasing me when it comes to ESB is almost impossible though because I think the colors that Adywan gave to his reconstruction of the '97 SE were practically perfect. Just please yourself with the colors for ESB, and I'll wait patiently for Star Wars. :-)
Hmm, I downloaded Adywan's Empire Strike Back a few years back and wrote it to a DVD. I've just found it and put it in my drive. I'm currently looking at his 8gb AVCHD colour corrected release of ESB. I've gone to that scene and can see what you meant about it being different. I have to disagree with you though about his colours being better. The colours in that scene on his version look wrong to my eyes, like he is forcing it to look a certain way, very neutral, the light sources looks off, it doesn't look 'natural' IMHO, only very neutral colourwise. Perhaps he has reference frames that suggest it looked like that on the film print but to my eyes it just doesn't look 'right' or even all that appealing. I know its almost blasphemy here to be critical of Adywan's releases and I expect to be flamed for it but those are my thoughts and I've always been someone to speak my mind honestly.
The last time I was this release was before I had my colour calibrated monitor or knew anything about colour grading so I couldn't really judge, so I remember thinking it looked good, much better than the blu-rays certainly. Now that I have a lot more experience grading I look at it again with my colour calibrated monitor and there are a lot of things I would do differently to him. His fleshtones are too red for my liking, his whites too blue, making the film feel too cold for my liking and the film overall is overly desaturated, all IMHO of course. Hopefully he'll improve the colours when his new Empire Strikes Back Revisited version come out.
If you consider his release 'perfect' it is possible that you will not like my regraded release of ESB. I have to maintain consistency in colour grading across the three films in terms of fleshtones and white balance, I would not be doing so if I did something similar to what he's done, but if you like what i've done with Star Wars, I do hope you at least give my grade of ESB a chance to see whether it changes your mind about what colours look good to you. The fact that you liked the scene after the chamber tells me you liked the fleshtones and white balance on my regrade so try giving the whole film a chance when I release it, you may yet be surprised. How I regraded Star Wars is very much dictating how I regrade ESB and ROTJ because they are all part of the same trilogy and therefore have to share some sort of colour consistency IMHO, so it follows that if you like how Star Wars looks, you'll probably like how ESB and ROTJ look as well.
Okay, feel free to flame away, I'm as ready as i'll ever be haha
