Hi everyone here!

I'm a guy from Barcelona, Catalunya, Spain, really interested in everything posted here in the forum. But much more interested in an issue I have because the particular conditions of my set up. Absolutely not the perfect one I wished.

The thing is I have a matte white coloured room with wood in the floor and some furniture from Ikea also a little glossy white, specifically that cupboard that seems designed to put vinyl records on it. My room measures 4x4 squared m (13,12 feet?) and I have my Epson 8350 (with the lens in it's wides ratio in order to get the biggest image) placed 3,7 m (13 feet) far from the screen surface, the wall itself, that has ,opposite to it, a window with a partially translucid glass that lets enter in the room some sunny light from the outside. This is not an issue itself cause i can mask it.

So, I was wondering, due to the specials conditions of my room and in order to achieve the performance of my set up what solution is better for me.

Since I've been reading here the Sony Dynaclear looks to be an option, as well as a BD II from SI, but i don't think spending my bugs in a SI while I've just ratailed the money in the projector. Seemeed It was better to get the latest entry level JVC projector... So, i Wondered: what about a DIY screen paint solution? I looked in the forums here in Spain and the mixings just don't convinced me so much since I've red almost every post from mech and it's amazing lightning and color revisions. Here we have mixes based in adding sparky particula on the final coat. ¬¬ And me myself have tried to paint a waterbased silver like formula (a metallic painture), that really makes me jump from the sit, but caused a lot of hotspotting and i notticed must be sprayed, because of the grain the image took.

The thing is I want to get something closer to the Black Widow or silverfire (any mix) that let's me enhance the CR (Contrast Ratio) of my projector and absorb the maximum possible amount of light in a way that i can feel the room more closer to a professional theater set up.

IS there any IBM patent not yet exploited that can do that for me? Is there any DIY mix that can absorb almost all the light as it seems it does the BD II in their video ads? Should I use any special coat to paint on the screen according to it.

I was thinking also in the latest release of the mixing of MississipiMan but the thing is I'm not an specialist, this is my -almost- first projector and I'm really lost in terms of High CR enhancement screens, reflection, color accuracy, etc... I mean, I'm looking for lort's of wow in the image preserving the blac as blackest possible.

Can anybody help me?

Thanks and congratulations for your work and time investment here in the forum,

Joan

Gotta go put a final coat on a 122'er. I'll respond in depth later on this afternoon.
(late night your time)

There is an answer for you...but if spraying isn't a possibility, the answers are limited in scope and overall performance. The differences between BW and Silver Fire are pretty wide. SF has more gain, and can be made to be much darker via the Colorant added to "taste", therin allowing for much better ambient light viewing.

But PJ placement /Screen size has much to say in all of that.

Is your PJ mounting option open to revision?

How Big a Screen dod you wind up with?

Basically, a very dark SF combined with a optimally placed PJ will serve you in the best stead...so answer those few questions and look for my response later.

Well, something i forgot to say is that the pj is actually on a library deep enough to handle it... but I can ceilling mount, no problem. And the screen I can't get more than 120", but I wish to move between 110 -120"... And spraying is not an issue, i would rather prefer "foaming", but, hey I'am a DIYer, I can learn!

Thanks guy! I knew would be you who was gonna answer

I've seen in Spain, in a forum dedicated to AV that contains painting mixes, someone has updated the most common formula there, the socalled Enigmax, I guess, and he is still using glitter on it, which i Don't undersatnd how it works, because you have to mix with a plain matte white painture, and, after it, uncoloured satin acrylic base; and apply it in a single coat.

Well, this is how things are here. But who posted the new formula argued that is almost impossible to find the same metallic components (the colour ones???) used in the s-i-l-v-e-r or Silverfire at wathever point.

I hope to make a handpicture of my room with it's measurements so you can keep it in mind before telling me to do one thing or another. I will hang it in a next post -I do not draw very well-

This is my room in a draw. I quoted 5 points, and that's why:

1. The window, which is translucid and unmasked. But at night it's not necessaire anf, if the case, i Will do.
2. The table that represents no problem at all just because i have the inwall light controller at the same height: 80cm/2.62 feet that makes me to locate the screen at least 1m (3.28 f) from the floor. Also it -table- reflects light because of it's glossy pine finish.
3. The cupboard, that reflects ambient and projected light because its glossy white finish.
4. The door, a full dark wooden one, that once closed it's not a problem itself.
5. And finally, the projector: Epson 8350 in it's current WW version. It's 3,6m (11,8 f) far away from it's front wall and it's placed inside the cupboard, mounted in the top of a rack inside the furniture, So it's no ceilling mounted. This is an important issue because i can ceilling mount but it must be at 2m (6.56 f) maximum, because i have the top of the cupboard and i just can put the pj reverse to it -in case of ceilling m-. Fortunatelly, the epson has the best lens shift ratio, but unfortunatelly they are manual so you have to sometimes readjust it. That's why is just in a rack i can easilly acces.

Now for a 110 to 120" screen 2'44 x 1,40m (94.5 x 55.1") and all this conditions, what's the best choice?
