Everything will be hidden behind a false wall and AT screen. I've got a full roll of black speaker cloth, and Seymour DIY fabric & Fidelo velvet are now en route.
I recently painted a good portion of my ceiling black with Behr Mouse Ears paint, and some very cheap black fabric for some touchup, and improved daytime light control . . . . As of now, pictures come out totally black even with window open and track lighting at max!
(I'm a camera retard though, should figure out exposure time . . .)
