Hello
I am using a projector since 2009. Always in a non dedicated room with white walls/celiing. So I am used to washout and contrast destroyed in high APL scenes even though there is no external light (fully blocked).
Now I have managed to reorganize my room getting a bigger projection surface (around 146" diagonal). My viewing distance is around 4.5m (screen around 3.2m wide).
Ceiling and side walls are close to the screen (a plain matte painted wall). So with bright scenes both ceiling and walls are pretty iluminated destroying my blacks.
I am considering to lessen this effect. I know that the good solution would be treat the whole room but as it is a common room is not possible (my wife doesn't want and I also enjoy a bright room).
I consider two compromised solutions.
1) I could treat the first meter of the ceiling with foams with black velvet attached with magnets (as I have metal joists in my drywall ceiling I wouldn't need to glue any magnet so a clean solution). And 1.5m of the side walls with black velvet curtains.
So theoretically I could go from a fully non treated room to a partially treated room without leaving any sign. Nice.
But, is this a significant improvement? Or just masking 1-1.5m won't improve the picture quality in the bright APL scenes?
Painting dark instead of the removable foam is also not an option...
2) ALR screen. To be honest I am reluctant to this solution as it is potentially a much more expensive solution (CineGrey 5d is 1800$ for a 145" screen) and also there is no guarantee of success at all.
I have seen a lot of youtube videos but they are usually referring to ambient light which I don't have at all. But I am not sure how this screen will reject reflections...
And also there is hot spotting, creases, and so on...
So spending around 2k and not fixing a problem is not a good deal. Actually I am still using an old DLP 1080p projector as it doesn't make sense to invest in a better projector until I improve the room.
In a near future I am considering a epson tw7100 (a tw9400 would be an overkill in such a room right now).
Anyway. I'd appreciate any comments about this partial masking. Any similar experiences?
I have read this article Contrast VS projector VS environment - Projection Dream and I have seen how amazing is the contrast in a bat cave. unfortunately they didn't the half treated room. Just full or none...
Thanks a lot!
