  1. Totally agree about the 3D brightness. It's the biggest drawback, and one of the reasons I'm holding off for another couple of generations. (There may be more decent non-converted content then too, you never know). In a way, a large part of his wow-response to the silver screen was all that extra brightness, and I'm pretty much getting that now with the Benq W6000. His JVC would've really needed help with its low lumens. But those screen shot comparisons revealed quite a raised black level, too. Cheers!
  2. Wow. Great job, sir! Thanks for going to the trouble. Meanwhile, here's an older thread which offers a pretty solid and useful comparison, and mercifully leaves paint out of the equation... http://www.avsforum.com/avs-vb/showthread.php?t=262466 (Too many google-searches is never enough.)
  3. And the Black Widow mix is apparently similar, which is why it interests me... "Black Widow is an N7.5 shade of gray with a .9 gain. It is just about a dead on clone of a Grayhawk. I say 'just about' because BW is actually more neutral and has a better color balance. If we increased the gain to over 1.0, that doesn't mean it would be a better screen! Viewing cone would start to decrease and the higher the gain the more chances of hot spotting." (Post #1217)
  4. Has anyone tried the "Black Widow" paint mix (or Australian equivalent) ? http://www.avsforum.com/avs-vb/showthread....97#post16930997 I'd be interested to hear what Australian paints you used and how you went with it. Thanks in advance!
  5. Very interesting. Thanks for that. In my case, room bounce-light onto the screen is very minimal, whereas the screen's bounce-back into the room is a much bigger deal. Surely, there'd be quite a narrowing of the viewing cone/angle with this, and at least some hot-spotting? I'll have a good look into it later...
  6. So, back to the real world, circa 2011... What do we make of this screen paint solution ? http://www.avsforum.com/avs-vb/showthread.php?t=1355246 I'm less interested in its performance with ambient light, but it gets very promising with the lights off! Some questions are answered here... http://www.avsforum.com/avs-vb/showthread....96#post20949196 Looks to me like it might be possible, after all!

  8. For the record, I've posted threads on three different forums... http://www.dtvforum.info/index.php?s=&...t&p=1739586 http://www.avsforum.com/avs-vb/showthread....41#post20932341 http://www.hometheatershack.com/forums/diy...html#post459566 ... Now, going through all the responses, there's a LOT of disagreement over whether a gloss mix actually works in boosting contrast / peak recovery / projected dynamic range to compensate for the drop in picture level when a gray paint is used! Here's what I think I know so far... * A gray screen is better than using an ND filter, as it will a
  9. Cheers Owen. I guess what I find hard to clarify is... * Can anything else be added to the mix to "recover peaks". (Gloss, satin polycryllic, maybe something else, but no metallic paints) That is, something that leaves the gray screen's black level intact, but adds gain as you move up the grayscale, until the peak white level is the same as it would be with a a white screen. * Does gray really reduce ambient light-bounce any more than a white screen?
  10. Dude, seriously. Like I said, show me one DI theatre that has a gray border around the projection screen. I understand your points. Whether or not I agree with them is beside the point. The point is that I'm asking some basic questions about screen properties and whether or not a painted screen can both drop black level AND boost contrast, and I really want to stay on topic here. Going down this road and debating these points is just a waste of time, and will scare off folks who I'm hoping will be able to respond to my first post.
  11. Man, I really really really don't want to go off-topic here, debating basics that I've known for years..... but I guess I've just gotta ask... Are you seriously suggesting that we should be viewing projected blu-rays with a giant illuminated border around the screen and ambient down-lighting, and that - assuming we're sending the correct signal to the projector & have calibrated the projector at the edge of black-crushing and white-clipping - that we should abandon any hope of achieving a deeper black level by projecting onto a darker surface? If so, take three steps, then get back to us
  12. I must say, I've never been in one post-production suite where this was the case. One or two grading / telecine suites, perhaps. At any rate, I'm not aiming to optimise TV, but film material in a darkened home theatre environment with masking! Have a click on my signature... Yep. I have a stack of test patterns which I've amassed and brought in from work. They're loaded on my PS3 for easy and quick access. I can see black alright!!! It's the lowest light output from a given projector, and the Benq W6000 is very good - but noticeably lighter/grayer than, say, one of the top-end JVCs.
  13. Yesterday, I finally got a chance try out a simple but hopefully effective mix. I have a Benq W6000, which is famous for its stunning brightness. I've been using a matte-white roller screen, which was replaced by a sheet of white curtain block-Out material (BOC) as a temporary solution when I moved and upped the screen size. (For the record, you can see the room by clicking on my signature below.) Although the Benq's black level is very good (better with higher contrast than many commercial cinemas, I should add), there's definitely room for improvement. A deeper black level would really t
