I need a screen that will reflect as much light back at me as possible

I need a screen paint that will reflect as much light back as possible yet still give me good contrast. Is this possible? This is for a large format curved screen with an aggressive curvature. Screen is 16 feet across but curved into an 8 foot diameter so the curvature is aggressive. I need light reflected back so that the individual in the middle gets light bounced back at them for illumination purposes.

What screen paint mix should I use to accomplish this. I need the cockpit to get ambient light from the simulation.

Thanks!

To do what / all that you want in a Painted solution, you will need both a dark Grey and highly Reflective surface.....the latter almost solidly into the Retro-Reflective range.


Been there...done that years ago. Why not now? Because in any such case, DIY or Mfg...there are caveats we / I as DIY Screen advocates don't like, or won't tolerate.


  • A decided Grainy look to the image, especially in lighter content areas (Sky...light Pastels...Flesh Tones...)
  • Overt Retro Reflectivity. This will be the lessor issue in your application...except for the next point.
  • Projector Positioning ( extremely critical if Retro Reflectivity is used )
Three important things for you to make clear:



1. What is / are the PJ/s being used?


2. What Material is to be used for a screen surface?



3. Just how much Ambient Light is there to deal with (Level of, and Type/Source/direction)


How about usage / content?


There is / are solutions.....but to select the best one...even a compromised one, more input is needed.

3 projectors using warping software


2. What Material is to be used for a screen surface?
Polycarbonate type material

Ambient light is totally controlled for now. Can be fully bright or total darkness. For this prototype its a completely light controlled environment. Once this goes into production it will more than likely be used in a convention center type environment.


How about usage / content?
Automotive simulation, heavy industry, aerospace, military

Answers above in your quote.

Any help is appreciated. I’m great at engineering mechanical solutions but the image is a tad more challenging.

Thanks

Here is my prototype just so you’re familiar with my work so far.
