So, i know for the DIY, when it comes to increasing contrast, one of the best ways to enhance contrast is to either A) use a greyish paint mixture like Silver Fire or such and B) When it comes to having a White paint top coating, you can first spray a grey undercoat then spray your white paint on top of that. And of course, we can't forget, you can do a Light Fusion of sort by spraying a white or grey top coat over a mirror or silver metallic. not to forget that a "white fusion" will also make contrast better but only due to the reentry of the white up kick. But what about having a black bottom coat instead or grey.
For a while i had to project my image onto my dark, flat, brown color i have on my wall. It killed brightness, that's for sure, but it was nice to see the dark colors so enhanced. I finally got my wall painted with a primer, to prepare it for S-I-L-V-E-R, and am enjoying having my brightness back up, but one they i do notice, is that in parts where the primer was a little thinner, due to the this and that, the contrast in that area is little better but still maintains its brightness in those areas where the primer was thinner.. Having the projector image light interacting more with that flat, brown undercoat, gave it a little kick in areas where the colors were darker. Blacks, and blue and so on where deeper.
I know these are the basics of painting when it comes to contrast and most are aware of these aspects, especially for those on this forum who have spent many years to give everyone a chance to have a good screen without having to pay tons for money for a GOOD screen by coming up with such formulas as mentioned above .
I know when everyone wants to get better contrast we usually stick with the greys but I was wondering what about having a small layer of black as a bottom coat then spraying a couple thin coats of White on top, so not as to rob to much whites. This is a big concern for me especially, because I have a 3D projector and when the projector is switched to 3D mode the brightness goes down about 25%, I think. I have the new viewsonic pjd5533w which I only paid $500 for and for that price it's great. It has 3000 lumens and contrast ratio of 15,000:1. But when it comes to paint mixture, I need something that doesn't kill my white so I don't feel like I"m loosing as much brightness, which really, isn't a much brightness but white i guess. But never mind the specs I'm loosing my train of thoughts, lol.
I would think that the biggest problem, of course, would be the extreme crushing of whites. But what if you could spray a high gain black that wouldn't kill it as much or spend some major money for a black diamond BLACK screen then spray a light coat of white over it., still giving awesome contrast and work awesomely in ambient light but giving some whites back to the image due to the white top coat.
Hoping some of the veterines in DIY on here, would give me a take on this. thanks.
