something to consider.
These masking systems, while wonderful and do make a difference, are very expensive.
I am exploring 2 other alternatives that I thought might be of value to others.
1) SI Black Diamond screen. Yes, this is an expensive screen but cheaper than a good white screen with a masking system. And no, it is not 100% black for the black bars, it comes close. An interesting alternative.
2) a black curtain that can pulled - manually or electronically - to accommodate 4:3, 16:9 and 2:35 material. Of course, this only will help the sides - not top and bottom. But if combined with a 2:35 screen, it can also be effective.
Thought I would share as these are 2 options I am exploring. (Actually, I am planning on doing both - BD 2:35 screen and motorized curtain later).
