Just to clarify, the area I was referring to which ends in Vader being seen to go down steps is behind where those crewmembers are looking on here. Where the steps led to was just barely out of sight here, but I always thought that the doorway to Vader's control quarters were just down there -

Which its get depressing how close are everything in a 20 Km ship :D

Well I stand by what I thought were reasonable and logical enough reasons for that which I listed in my 1st post on this page here - http://originaltrilogy.com/forum/topic.cfm/STAR-WARS-EP-V-REVISITED-EDITION-ADYWAN-NEW-TRAILER-AVAILABLE-NOW/post/385576/#TopicPost385576

.....and I've always assumed that the other stairs that went upwards on the far left of your 'dimming lights' shot led to other areas that would access the rest of the large 'tower' they are in, with lifts to the main bulk of the ship itself (there's certainly a doorway on the left just as Vader enters the 'control room', as well as one further along which would give access to that side of the 'tower', and there would be some on the other side too)....but I guess we'll just have to wait and see what Adywan reckons for his version.

Vaderios, there is indeed a momentary 'dimming' in this shot, and it's on the GOUT too. It looks as if there was a deliberate (?) slight dimming of the lighting above the main walkway only.

So what do you think? requires fix? Or its a trick so the eye move off from the background?

Not sure about it either way vaderios, but it doesn't look like the whole shot has darkened, but only that the lights above have dimmed a little. Could be a couple of reasons why the 'Executor's lights might dim I guess.
