How much light would be getting through 2 layers of Spandex. I was planning on attaching the spandex to the frame sometime this weekend. Now I am worried about my build.
I have a lot of space behind my screen that is for storage with shelving, electrical panel etc, with plenty of reflective surfaces. Currently I have been using a cheap outdoor screen but it does not let any light pass as it has a dark rear cover. I am worried about reflections back to the screen. I have about 3-4 feet of space behind the screen between the frame and any of the surfaces. Should I could cover the back of the frame with some sort of blackout cloth, or black spandex to absorb any excess light instead of reflecting it.
I cannot change the location of my screen and keep the WAF going.
