So that leads why vader went from his chamber to the spot and didnt came directly from the door . Its like entered the door, entered the chamber, came out from the chamber to push the big button on the floor.
Okay vaderios, here's the stuff I wanted to bring up about the Vader/'chamber' shot...so just to recap, here's how it currently fits into the flow of the movie -
Vader quickly rounds the corner at the end of the 'control room' section that's just beyond the 'bridge'...


...then we immediately cut to the Executor moving out of the asteroid field...




...then we immediately cut to Vader descending the steps of his 'meditation chamber', as he walks towards the smaller, circular prop...




...then we immediately cut to the Emperor's 'hologram' appearing...


Some thoughts on all this -
Firstly, I've always preferred to think of the entrance to the 'meditation chamber'/'hologram' area as being *just around the corner* from the 'control room'...so that Vader is always close to the the 'action' and 'running' of the 'bridge' when he's aboard. And these particular shots below always give me that impression, as they seem to work reasonably well with this notion -
Here's the end section of the 'control room'...

...and here's a different view of it later in the movie, where we see Vader go down some steps just around the corner of the same set...



...and this earlier shot of Piett below shows how the steps outside the guarded entrance could be regarded as being the ones that Vader goes down in the shot above... (and Veers is picked up off the floor by 2 guards near the area shown in the shot above, which ties in the guarded door shot shown below, too)...

Unfortunately, I don't have the 'behind-the-scenes' pic of the the outside of this 'guarded doorway', that was posted here a while back...as it gave a good idea of the distance down that the doorway is positioned away from the start of the stairs - my point being that I've always been fine with 'imagining' that the entrance to the 'meditation chamber' is therefore situated somewhere immediately behind where Vader is standing here, in this shot below...as the 'chamber's surrounding room dimensions could plausibly fit down there just fine, behind and below this section of the set...

...and another reason why I've always liked the notion of Vader's 'meditation chamber' being situated *near-at-hand* to the main action of the 'bridge' and 'control room', rather than much further away somewhere...is that when we cut away from the shot of him quickly turning the corner...and then transition to the shot of the Executor moving out of the asteroid field for a few seconds afterwards...it just *seems* when watching the movie, that there's been just enough time for him to have briskly gone down the steps around the corner and entered the area where the 'chamber' is, in 'real-time'...by the time we cut back to him...
However, I acknowledge that a different thing that can be 'imagined', is to look on the cut to the Vader/'chamber' shot as being a sort of *jump-ahead-in-time* moment...which occurs some unknown time after we've seen the shot of the Executor move out of the asteriod field...giving the impression that Vader walked further away from the 'bridge' to reach his 'chamber'/'holograph' room... Not that I prefer this alternative myself, although it can work too I reckon. Having said that, the current view seen outside of the 'chamber' doorway during Piett's entrance doesn't necessarily need to be altered, for anyone that wants to 'imagine' that the room is located further away from the 'bridge' after all...
But the MAIN thing I want to bring up here is this: as you mentioned vaderios, the way the shot is currently filmed gives the impression that Vader is coming down from the direction of the 'chamber' itself, for some unknown reason, before he addresses the Emperor... It's something that kinda makes my preferred way of 'imagining' this overall sequence playing out in 'real-time', a bit off...as the Executor shot would have needed to go on just a little longer to allow plenty of time for it to work better...because Vader looks as if he *did something* (?) inside the 'chamber' first, and would have needed just a little more time to do so, in 'real-time' onscreen. This doesn't make me want to change the way I prefer to 'imagine' the 'close' position of the 'chamber' in the general layout, though...but I accept that the alternative idea that it's a little *jump-ahead-in-time* moment due to the 'chamber' being somewhere further away...probably works better to allow for the extra time needed for Vader to go into the 'chamber' and come out again, that the existing shot implies...
...which is why I'd have liked it to have been cut slightly differently in the first place...to resemble something more like the way I've shown below. Now I know it's sacrelige to suggest removing even one single frame of ESB, lol...but in this case it would have certainly helped with putting Vader into a more likely position in the 'chamber' surroundings, to match my preferred 'real-time' layout...by the time we cut back to him after the Executor shot! -
Vader quickly rounds the corner of the 'control room' section as normal...


...then we cut to the Executor as normal...




...but we now cut to show Vader only *just about* to step onto the smaller, circular prop...rather than having him descend from up on the 'chamber' prop first...so that it instead *seems* like he walked directly over to it, once he entered the 'chamber's surroundings... (there would be a brief, minimal loss of 'music score' at this point, of course, that would need to be smoothed to fit)...



...we then cut to the Emperor's 'hologram' appearing as normal...


On the other hand, it's a reasonably iconic shot of Vader I guess (aren't they all?), and gives a good angle of the 'chamber' prop...so I can understand if adywan and others would hate it to be tampered with. Thing is, I always 'imagined' that the 'holograph' transmission only came on once the smaller, circular prop was 'activated' by Vader stepping/kneeling on it...although the full Vader/'chamber' shot gives the *impression* that Vader did something else in the 'chamber' first, before descending...
Did he have to 'activate' the smaller, circular prop from the 'chamber' itself first , before it would work? Or might he have had to give some 'command' or other to someone on his 'viewscreen', first, before switching it off again? I'm interested to hear what anyone else thinks Vader might have been plausibly doing, before addressing the Emperor...that makes sense in the context of how this existing shot was filmed...
