I've decided to paint 3 walls plus ceiling in Dulux Cookie Dough
And the wall that I'm going to projects onto is going to be a 4:1 mix of Dulux Matt + Hycote Alliminium
How long would you guys reconmend I leave the plaster to dry before I paint ? Its been dryin for 5 days now.
I'd wait long enough for the cracks to appear
If the heating is on a few days should be sufficient for the plaster to dry out. Unfortunately I can't be too specific on the paints I used, it was a long time ago and I dare not read all of the threads again. As long as you follow the most recent formula I'm sure you'll be OK, Custy et al know what they're talking about.
Here's a screenshot taken from some testing I did a while back, I posted it on AVforums but can't find a link to the thread. It shows the different types of black and white levels (as well as colour differences) from differing fabrics all of which all have various gain. You should be able to get a good idea from this what type of picture you can expect as you lean towards off white.
Check out the blacks on the Disney screen shots, they show the power of a good grey screen.
I'm gonna have to have a closer look at this, I'm a casual projector user @ home and don't have a dedicated room, I've always found the image more that acepable on my white wall (I'm happy to turn my flat into the bat cave LOL), as with others that posted and I assume most casual projector users cheap option's are a first step (Paint, sheets, blackout blinds etc, Must Break your Heart!) but maybe would be prepared to have an experiement with gray if costs and effort were reasonable in an effort to improve picture quality.
I'd be happy to stick a sheet of mdf in a frame, Would you offer a general paint mix that the heathan's among us could try?
So is your latest stewart screen gray?
@Penners please let us know how much you think the image is improved.
Sorry but I am unable to enlighten you with any words of wisdom regarding paint choice, you'll have to figure that out with Penners
evil: Maybe you could work shifts to read the mountains of info over at AVforums, I have a wife and kids that need me over Christmas not to mention all the imaginary charity work I'll be doing.
I'm working on my dedicated room now, well dedicated means gym/cinema room and I will not be painting my walls black, that is for hardcore HT aficionados. I've tried blackout blinds and they work great, if you decide to go down the bat cave route I can assure you either you'll turn into a goth or Mrs Hejira will divorce ya.
Months of testing showed me there is very little between screen surfaces and a plain white wall almost works as well as a high end matte white screen. Either way I would worry too much thinking you are missing out on spectacular imagery just because you've gone the budget route, most of the 'maximising image contrast' posse are anal over the tiniest of details that make minute differences. Just make sure there is no stray ambient light shining directly onto your wall and you should be OK.
I'm using a curved 2.35:1 Stewart acoustically transparent screen. I did some testing with speaker placement and found that the largest gains in terms of viewing experience come from having the sound fired at you from the screen itself. So I made cutbacks on PJ choice, speakers and everything HT related and used the money saved on an AT screen. I ended up will mainly second hand gear but I didn't fancy shelling out three grand for a piece of fabric and more on speakers. I still have my G3, it will end up being a hand me down to my mum as it doesn't cut it for gaming. In the gaming room/loft I use a Draper high power screen with a 2.8 gain, it makes FPS games playable without having to turn all the lights off or you can watch TV with a few guests with just dimming the lights a tad. Bat caves are anti social..
