Wow that looks really much better than a normal viewing area, thanks for the pics. they show the benefit of even blacking out that much of the room. Could you kindly maybe show an example of how the image/movie looks when you turn of all the lights in the room (just a normal movie shot maybe a dark scene or something? And also another request if possible, how the image looks in a very bright scene, does the black velvet do enough to absorb any brightness, and also is 4 feet enough to stop any brightness, because i've seen many videos of normal rooms where bright movie scenes seem to reflect way more than 4 feet.I purposely blew the second picture out so you can see it, but I did exactly 4 feet out from the screen plus the back wall. Lots of strategic patches on shiny speaker parts, the edge of my computer monitor on the right, etc. It's a true multi-purpose room (that's actually my office space to the right), but I can get it extremely dark and while it would be nice to have a full cave, or may even go 8 feet out, it's pretty immersive. It was also way more of a chore than I thought (ceiling was brutal), with all the baseboard, sump pit on the left, water valve shutoff cabinet above that, etc. Now that I'm out 4 feet, the rest would be a lot easier...I just ran out of desire and and adhesive velvet isn't cheap.
I used the McMaster-Carr adhesive velvet which is massively absorbent, to the point it's difficult to see without the lights way up.
Lastly, you mentioned you used adhesive, isn't that going to be a very big job if someone wanted to remove the blacking out later on?
Probably would have to paint the ceiling all over again
