Well let me give you a reality check.
1. The material will not be able to be put together to where it shows no seam. That would require not just a virtually perfect union, but a "perfect' one. Anything less and the junction line will be visible due to the nature of the retro-reflectivity properties of the surface, as well as the loss of such at each of the adjoining edges.
2.You've bought into the visual hype that any such screen presents, Much like a High Power, if your seating is confined to within a 30 degree arc from center, so you situated directly in front of the Screen....it works. Big deal....other screens have presented similar performance, and in this case both gain and the darkness of the layered material are the factors.
But step just 15 degrees off center and.........
3. For any screen as large as you desire, the method employed by the BD is not feasible. That should be evident by virtue of the fact that they do not make the surface larger than 80". Once again, viewing angle is the factor, and is also joined by the screens lack of brightness at the edges due to it making any difference in the projector's uniformity of projected brightness from the center to the edges quite obvious.
DIY applications are intended to be much more flexible. If you want similar performance, such as overt brightness, spark-lies to the excess, a grossly limited viewing cone....we can oblige. A surface sprayed uniformly with a dark gray, heavily imbued with silver/pearlesecent/poly mix, or one with a excessive amount of aluminum...also sprayed uniformly, and wonder of wonders.... and there is would be. Right along with all the caveats Local Zone is dealing with. At least you wouldn't have to deal with those seams.....
It's just that we are not inclined to develop such limited, restrictive, and singularly oriented designs.
No....we are better than that.
Simply put, we DIY'ers all want and desire things we really have no way of obtaining.
Ultra Fast cars under $1000... drop dead gorgeous women (or men) who expect no special treatment...luxury homes at shotgun shack prices...bodies that don't show the signs of excessive living. And mostly, DIY screens that cost virtually nothing, and perform miracles of physics.
All the above demand some degree of sacrificing one thing to get another. To my/our way of thinking, it's better to have reasonable expectations, and achieve them as obtainable goals, than to squander our efforts on trying achieve what even the Mfg have no way of accomplishing.
But in reality, we come awfully damn close, and in the case of larger screens, I'm stating we EXCEED what Mfg can offer, and we do it at ridiculously lower price points.
Now, quit dreaming and determine what it is you actually need. I seriously doubt you'll ever watch any content under full, direct lighting, nor limit yourself to sitting dead center in front of a picayune 80" screen. Instead. consider that those 3 year old examples shown are done in extremely high light levels, some are taken at a viewing angle FAR in excess of what Local Zone or any demo example of a BD screen has ever shown, and that the White screen is in fact a White Light Fusion (painted mirror) and it's doing a not so bad job showing a image under some pretty intense lighting.
The Gray panel is just Silver Fire painted on white hardboard, done solely to illustrate a point.
So let's see what real world stuff can be accomplished.
A collection of various Gray test panels.
Examples were shot in 75% room lighting Be sure to note that these are metallic and non-metallic Grays being compared to a metallic Gray...in this case the underlying 135" screen is a early Black Widow example
Here is a Silver Fire 2.0 (N8.5) screen being compared to a white panel, and the same tes panels as seen above in the previous shots.
First, the Screen in ambient light all by itself.
A bright TV image is the easiest to get by with of course. The comparisons below are all "dark" movies.
First...the panels in high ambient...as in really high ambient light.
Now with a image.
A very telling shot of Black Space,
These next ones show the panels under ambient in the large image, and ambient on the left smaller image...while in the dark on the right smaller image.
Night Sky Fireworks in high ambient light....
..and in a dark room setting.....
Now following up, here's a 135" Silver Fire 6.0 screen w/Optoma EW1610 pj
Just take a look at this shot taken with both large Globe lamps fully lit, and just 6' directly in front of the screen.
This next shot (...taken in the dark) shows how very little drop off in brightness this DIY screen has. At the angle shown, the Black Diamond would be absolutely unwatchable, even in the Dark.
This last one is taken in the degree of ambient light the screen is normally watched in, with the most forward of the Globe lights turned off. Even taken from over 70' away, and with 12 huge lights between the camera and the Screen, please note the Screen's brightness actually overdrives the Camera's meter because it's directly opposed areas are so much darker, yet the ambiet light ahead of the Screen isn't affecting the screen's performance enough to matter, let alone offset that effect. But a close observation shows the Room's lighting is definitely illuminating the room's surfaces all around the Screen.
Now then...you go looking for ANY promotional shots of the Black Diamond screen being shown under anything remotely like the images shown here. It will be a fruitless effort, lemmie tell ya!
After you return with no fruit in hand, we'll get you hooked up with a meal with some "real world" meaty fare to chew on.
