Okay, I've stuck all this together into a single post now so that's it's easy to scroll up and down to compare how things look at a glance. Some of the proportions may not be perfect, but I reckon the general look of asterisk8's rough layout makes sense of things pretty well -

Due to the deceiving angles that the 'meditation chamber' and 'holographic' scenes were filmed at in certain shots (especially as seen in the large shot 16 below), I was never really sure if there was a reasonably plausible way of tying the set(s?) together logically as a single room, to make better sense of what's currently seen onscreen.

But as I mentioned yesterday, I'm now fully onboard with the notion that the room can indeed be 'imagined' to be an almost '8'-shaped area which is 'narrower' in the middle, and comprised of 2 roughly circular areas. So here's a selection of some of the relevant shots which should help to remind everyone how things currently look, and which reasonably back up this '8'-shaped solution, if you choose to look at it this way. Which I personally will, from hereonin, so thanks for that guys! :)

1. Let's start with the scene where Piett enters the area to glimpse the back of Vader's scarred head. The doorway seems to be to the 'side' of the 'meditation chamber' in this view, and happens to be just out of shot in other certain shots of the 'chamber'. The doorway section gives the impression that this side of the room may not be as 'circular' as the rest of the wall that surrounds the 'chamber', and that this area may not necessarily be symmetrical. Alternatively, it could be 'imagined' that there may even be another , matching doorway on the opposite side (which we just don't see in any of the shots), and that the area here is perhaps symmetrical after all. I prefer to look on it as just having a single entrance though. It doesn't matter at the end of the day, as this half of the '8' shape is still roughly 'circular' overall, whichever way you look at it...

2. ...Piett then has to turn to his left to walk around to the 'front' of the 'chamber'...and seems to take a step up onto what I reckon is the bottom step of the 'chamber' prop, before he eventually stops. So the floor remains level throughout the imaginary '8'-shaped area... (see shot 15 below for a decent look at the 'chamber's' overall base shape)...

5. ...and at this point he is just about fully facing the 'front' of the 'chamber'... I'm okay 'imagining' that the background here represents a 'distant' portion of the back of the 'other' circular space where the 'hologram' appears. (also see the Veer's 'close-up' in shot 11 below too, for another example) Just a thought adywan, but although the background wall detail in these particular static 'close-ups' of Piett and Veers is already slightly 'out of focus' to begin with...perhaps adding slightly more of a 'blur' to them could further enhance this notion of it being the distant 'hologram' wall area even more?... I'm content will things well enough here, if not though...

6. ...and there's a 'direct onwards' view of the 'chamber'...and the 'viewscreen' is inset into the rounded wall directly behind it...

8. ...the edge of the 'viewscreen' can be seen here in this particular shot of Vader looking at Piett...

9. ...and then there's another 'direct onwards' look at the 'chamber', which again doesn't reveal too much of the set's surrounding wall shape, so nothing is contradicted in this particular overall 'circular' area where the door positioning seen earlier is concerned...

Okay, here is the scene from earlier in the movie where Veers visited Vader -

10. ...again, we see a 'direct onwards' view of the 'chamber', with the 'viewscreen' behind it...with just a hint of the surrounding overall 'circular' backdrop revealed... And like Piett eventually does, Veers is standing somewhere at the 'front' of the 'chamber'...

11. ...and again, I'm okay with 'imagining' this backdrop to be part of the 'holographic' circular area in the 'distance' in front of the 'chamber'...

12.

13.

14. ...and Vader's centrally-located chair swivels around, as he turns to look at the 'viewscreen' that's on the wall that's directly behind the 'front' of the 'chamber' from this view..

And just for comparison's sake again -

15. ...here's the shot of Vader when he approaches the smaller, circular platform that's positioned at the 'front' of the 'chamber'...and it's still easy to imagine that the 'doorway' is offscreen on the right of this shot, to tie-in with the Piett shots at the top...

16. ...and here's the 'side onwards' shot again too, to confirm that it can just about be 'imagined' as being another circular area, and the 'other' half of the '8'-shaped room...

adywan, I read your answer about the darkness of the shot here, and that's fair enough. However, if you *were* to add a 'hint' of the 'chamber's' lower step into the bottom left of the frame here, perhaps any white/grey 'shiny reflection' that's similar to the one on the smaller platform would make it stand out enough to be noticed?

Okay, that's my lot for this year folks, so I'd just like to take the opportunity to wish Jay and all the members of O.T.com a very happy New Year! And I hope all goes well on the family front for you adywan, in the coming days. The edit will be ready when it's ready, and definately be worth whatever the wait. 'SLANGE!' (raises glass)
