Hi! First post here after alot of reading. I would like some advice regarding my diy screen painting.
I am in the middle of my first attempt at building a screen for my first projector (Infocus X9, rated at 1800 video optimized lumens).
Since I have a pretty bright projector, and i wasnt really happy with the black levels with what im using now (white wall), I decided to try and build a Black Widow clone. Looking at other peoples screenshots, and comparison with other gray screens, it just seems to be a very good choice.
What i did was build a frame out of wood and then stretched artist canvas over it. So far so good.
Then I got the AAA paint, and what i have understood to be the correct color for europe to mix it with: s0907-y70r.
I wasnt sure what shine to get it in, so i got it in level 5 gloss (flat or matte is like 3 over here, and regular wall paint about 7).
I then painted a small testpanel with AAA s0907 1:4 concentration to see what it would look like. I made a bach of 1dl of AAA, and 4dl of s0907, that is correct right? Now, here comes the problem:
The whites are not even close to white. They look almost as gray as the testpanel does really. This is especially noticable in bright scenes with lots of white content, and even much so when i connect my xbox and try to play mirrors edge (which is a very bright game, with lots of white, bright scenes) Granted I am comparing to the white screen (I know this might confuse the senses a bit), but is it really normal that whites looks like noticable gray when using gray screens?
Comparing to a gray piece of cardboard I have that is about the same darkness, the whites look almost the same as the BW paint. Seems the aluminum isnt helping at all in my mix to me. From most screenshots ive seen of the BW screen the whites look much better than it does on my testpanel.
Can I make the BW mix lighter atleast to make it less apparent that the whites are actually dark gray? Like 4:1:1 or 4:1:1.5 using white paint in the mix to lighten it?
Or am i expecting too much from this mixture?
Btw, my image size on the wall right now is 104" diagonally, and according to the projection calculator over at projection central, that should be around 52fL on my white wall. Plenty of light output, right? (I normally turn down the brightness during nighttime viewing, and run the projector in eco mode)
Will the upcoming lighter BW mixes also be based on the same colors+ added ingredients, or completely new ingredients? Im trying to decide if i should keep most of my expensive AAA paint until I can make a lighter version of the screen if its not advised to just add white paint to it.
Thing is, I am using the projector in my living room, have white walls and ceiling. So the added benefit of ambient light rejection with a darker screen would really be at good use here if i could only get it to work for me.
Any advice on my situation what to do would be greatly appreciated.
Thanks!
