Well, first off, and for the sake of dickishness, Shit Yeah it lights up! It's very brief, just at the tail end of 7:18. And the following corridor doesn't light up right away to imply distance. We're meant to buy into the idea that even that chamber at the core of The Death Star is several kilometers wide and the Falcon, capable of ridiculous speeds, is outrunning the explosion and beats it there. It does start to light up in the very next shot. You might say that at least the light from the explosion should beat the Falcon to the corridor, but the surface it would be reflecting off of is where the camera is positioned... and if it lit up completely realistically, it'd be too bright to see anything.Bad Jim said:
Watch carefully as they blow the core up at 7:18 - 7:19. Despite a substantial explosion, the chamber walls do not light up at all, nor does the tunnel they escape into. It's quite clear that the explosion has been superimposed, and this is the most significant explosion in the whole movie.

But that's beside the point. That's not the type of lighting I'm talking about, and I don't think there's an adequate way I can describe it. I'm talking about the way light acts in between the model being shot and the camera recording it, and how it looks on film. I mentioned before that I have been fooled by digital movies to think that some things that were real looked like CGI, because digital photography receives light differently than film and treats it more similarly to its simulated CGI version. I find that it blurs the distinction between the two, admittedly making the CGI look more realistic, but making the actual real stuff look less so.
Despite more "realistic" lighting and movement techniques employed, I don't see how is how this
looks any better than the pan shots in that ROTJ video between 2:18 and 3:08, or the dives from 5:02 to 5:20. It just has more stuff happening and faster. It looks synthetic; the movements and lighting are too perfect, they feel programmed. The added motion blurs stick out like a sore thumb. The ships appear to have no mass and their texture is tooo... shiny? oily? Like I said, it's hard to put my finger on.
It is true that the edges don't look quite right, if you're looking really close - but that's the same argument that's been thrown my way when criticizing CGI - having to look really close. Things are generally happening too fast and I'm too involved in the story to focus on the small imperfections. This is also why I do forgive a lot of CGI (though it doesn't really get by me the way imperfections in practical effects might). I should reiterate that it isn't small imperfections that fuel my distaste for CGI. It's not what the objects do, it's how they look.But . . it's not the real deal. It's chroma keying. It's just as fake as CGI. The edges never look quite right.
The difference is physicality - it's not as fake because the CGI ships don't have any. The model ships are physical objects and the explosions are real explosions (even if they're not superimposed all that well; I would definitely consider those explosions to be the weakest link). In my experience, the human eye can tell the difference. Though, like I said before, it's possible that some can't.
