curtains system, which, when pulled, covers simultaneously both the two side walls AND
the ceiling. Here's what I mean.
Exactly like in the video, I'll be projecting in a room which will be totally darkened through roller shutters.
And, like in the video, I would like to reduce reflections through room optimisation.
To try and achieve a similar result, I came up with the idea to
- paint the ceiling with dark paint
for about 2 meters (80inches) from the screen
(this would be the color of choice https://www.meinonlinelager.de/capar...cid-48565.html
- install along both side-walls some IKEA Black Tupplur roller blinds for 3-4 metres (120-160 inches) from the screen https://www.ikea.com/it/it/catalog/p...113/#/30349126
. The black Tupplur would be pulled down only when we project - i.e. after the room has been already totally darkened.
1) Do you think I would this way achieve a result similar to Anna&Flo's when I pull down the 2-4m of Black Tupplur on both sides of the screen? Do the Tupplur have absorbing properties ?
2) My VPR is a BenQ W2000 and it is installed on the ceiling at 3m of distance from the Cinegrey.
My room is 7m long and I sit 3.5m away from the screen. How many meters should the the curtains/blinds cover ? Will 3m be enough or do I need to cover more since I sit at 3.5m? How many total meters of triple black velvet curtain (to cover both side walls plus the ceiling) or IKEA Tupplur blinds (to cover only the side walls) should I purchase ?
3) I have noticed that even when Anna&Flo’s triple curtain is fully opened when being used, the top curtain is floggy and hanging (it is not tense/straight). can anyone think of any reason why Anna&Flo would not install it in such a way that it would be straight once it is open and being used ?
4) how many CM/Inches higher than the top edge of the screen does the top part of Anna&Flo’s triple curtain need to be installed so that when it’s closed (not being used) it doesn’t hang in front of the screen , thereby covering it?
5) once I have optimised my room with Anna&Flo’s triple Black velvet curtain system or the “Ikea Tupplur blinds + dark painted ceiling” , do you suggest I still use the Cinegrey 3D or will there be no use for it ? If better to replace it (since it may deliver duller whites) , what screen would you suggest I buy ?
Many thanks for all your kind advices,
Glad you like our system.
We actually build it when we were in Munich. When we moved we took it with use and rebuild it in the new appartment.
There we paid even more attention so that the upper curtain is well tensionned.
Here are better pictures of our retractable tunnel:
Since then we moved again, and we are now using a DNP Supernova Blade 08-85 in 120inch. Pretty awesome piece of material withe excellent vertical light rejection and virtually no sparkle at all (and I am very sensitive). But we don'T have the same black hole immersion anymore. It will come back when we build our home theater in the ceiling... in the future
Have a read there for more pictures:
So a few answers:
You will definetly see a big improvement over having a room with white wall and ceiling even if you only paint in black your ceiling and use black Ikea tuplur for the side.
But NO, it will definetely not give you a similar experience or contrast boost to what we or
achieved with our "Black Velvet Tunnel".
There is a good reason why 90% of the people in this thread use "Black triple velvet" or similar: it absorbs light in a impressive way with the tiny hairs it has.
The result with TBV (Triple black velvet) is maximum contrast AND maximum immersion --> the room disapear: you don't see the ceiling or the side, even if they are very close to your screen and even if it's a very bright scene projected on the screen.
With black paint and black tupplur, it will still reflect A LOT --> not good for immersion, and not good for contrast --> but much better tha white walls.
Nice projector. Anna and I liked the BENQ W2000 a lot when I tested it. Sharp and relatively silent for a DLP. Especially because it had crazy good ANSI contrast for such a low cost projector.
This chart should show you how important it is to perfectly optimize your room, even with a DLP, if you want to enjoy it's strength: ANSI contrast.
Otherwise the contrast get lost.
3m from a the Elitescreen Cinegrey 3D is however because it will create massive hotspot. Plus the cinegrey 3d and 5D show clear sparkles/shimmer on clear bright background, especially if you are sitting only 3.5m away..
If you can optimize your room and get rid of it and replace it with a good lambertian white screen (Elunevision Reference Studio 4K 100 has an excellent quality/price), that would be much better!
We had the same sitting distance that you have. 3.5m away from the screen. And the curtain covered the first 3m. That's enough to cover what you see for full immersion and get close to the max contrast. We had about 90% of the ANSI contrast measured at the lens on the screen.
Well, the upper curtain was not perfecty tensionned in the first setup because it is damn hard to have the PERFECT curtain+ring width. If you make it too short, well it will not work at all. If you do it at the perfect width, it may not slide on the side because you have to much tension and friction. Too long, it will drop.
The second time we build it we had better success as you can see in the picture posted in the begining.
We did not want to have to many bars /rails at the ceiling, but if you are ready to have one in the middle you can use 3 bars instead of 2 to support the upper curtain.
I'd say we had only 5cm drop the second time we buiild it. Maybe 10.
If you optimize your room perfectly, then defnitely, get rid of this screen! You are currently getting hot spot and sparkle with it. As I mentioned above, the Elunevision 4K studio reference 100 is very good. No structure at all, very similar to the Stewart Snomatt 100 at a fraction of the cost. Light blue shift to it (like may other screen out there).
If you can, the best woud be to reproduce 1:1 or better our system.
If you can't, at least it would be much better to replace your idea of black paint on the ceiling by some Black Auto adhesive velour DC-FIX or even better: protostar.
Don't forget to have a black carpet for the floor.
In our setting, it was the only thing we were seeing in the movie, since the black carpet was clearly not as good as the triple black velvet.
Also don't forget the wall begind your back if it's still close to the screen. Here some dark paint would be enough.
And on a side topic, if you don't have a masking system yet, you should make sure that you get one! This increases the subjective perceived contrast A LOT!
Especially with a benq w2000 which has a relatively low on-off contrast. Masking system will make your black bars disapear.
It's even more important if you go the route of all black optimized since these black bars will look (even more) grey in comparison!
