Actually, the issue I have more than anything is the color correction. Well, the image characteristics, anyway. The colors are fantastic. Hoth is white, but I'm glad to see that there is some blue in there, because there should be a tiny bit of blue in some of the shadows in certain scenes as far as I can tell, same with some of the Bespin duel. The issue really is one of contrast. The image is way too punchy. It looks like its the 2004 DI with balanced colors but nothing else. Usually it looks quite nice and makes the image seem sharper, but the black levels gobble up detail, the contrast is about 10-20% higher than it should be, and certain scenes have strange balances, for instance Dagobah seems to be a lot brighter (and blue/green-er, compared with the GOUT, which I still hold as the most reliable color reference; strangely some scenes here looks LESS contrasty than the GOUT). I'm being extremely nitpicky here, of course--this transfer is so good that any complaints have to be! If there ever is a 2.0 version of this done, it would be nice to have the midrange a tad brighter in most scenes to reflect the original photography. ESB was always the most contrasty in its lighting, but it was never quite this extreme. The saturation is also about 10-15% too hot, as usual with the 2004 balances.
Anyway, hate to complain, because like I said this was the most fun I have ever had watching ESB in as long as I can remember. There is a shot on Cloud City where Han and the gang are walking away from the camera towards an orange glass wall, just after they arrive, and I know Adywan you must have rotoscoped around the actors and dropped in the original orange wall, but for the life of me I can't see any of the seams. Its flawless. Bravo.
As far as I can tell, these are the things in the film that are still "altered":
-Hoth speeder recomps in all the scenes they are in, including Imperial Walker fight
-Imperial fleet introduction has recomposited elements
-Any asteroid chase recomps
-Falcon cockpit croping
-Han's shirt during the carbon freezing
I think there is one or two shots of the Falcon approaching Cloud City that have been recomposited for the SE (such as when it passes through a cloud) that remain as recomps. So really, aside from recomps, which might be best to leave as they are in the SE, Han's shirt is the only actual live-action alteration/addition that remains. If Adywan takes a second pass at this, I hope he gets rid of this one thing (adding in the shadow area should be easy, since there is little detail). Also, there is a shot or two in the duel where Vader's lightsaber core is still dulled down ("Your destiny lies with me Skywalker" shots in particular), if you want to count that.
There were also a few weird things I noticed--scratches in the recomped GOUT area. The GOUT shot of the wampa fur moving in particular has a lot of grain and dirt that is visible, I'm guessing this was left so as not to erase the detail on the fur (the previous GOUT shot of the shadow on the wall looks clean, but only because the white walls hide all the detail scrubbed away), and there is a shot of Lando and Leia running through a corridor where a hole/scratch appears in one frame in the recomped wall section, which stood out to me. Just pointing it out, for what it's worth. The other recomps are fine, although the establishing shot with the cloud car looks like it has some wobbly rotoscoping on the car at the head of the shot, must have been a pain to track it in.
Anyway, always feel guilty nitpicking this. You've done some fine work here Adywan!
