  • But when I watch a movie, the “black” that I’m seeing in a particular scene isn’t the absence of light, because it’s not actually “black.” It’s a very very dark shade of grey or brown or whatever. And that requires light.

    What you’re seeing are the deactivated TV pixels absorbing light. This doesn’t work with a projector screen because the screen is of course designed to be reflective, otherwise you wouldn’t see anything. Point a projector towards a piece of black velvet and you see… black velvet.

    Even if there is some actual “black” (spots where no light is coming out of the projector), there will still be a gradient, and immediately after “no light,” you will have a light attempting to project a very dark shade.

    This is the contrast I was referring to earlier. It’s basically the accuracy of the projector in defining a limit between the areas it’s lighting up. But if you do this in a room with the lights on and the windows open, the image will be completely washed out regardless of how high the projector’s contrast is.


  • Is that true? Because I was under the impression that even the darkest “blacks” from a projector, are still made from the light coming from the device

    You’re probably thinking of contrast, which is the ability of the projector to avoid bleeding light into areas that shouldn’t have any. But as far as the darkness of the black levels, that’s down to room treatment (and the screen surface, to a lesser extent). After all, a projector emits light, and darkness is simply the absence of light. You can’t “make” darkness, you can only remove light.








  • This ties into the age-old debate about platforming bigotry in the name of free speech. Bigots don’t care that much about talking with like-minded people — they want to subject others to their beliefs and to feel as though they are a righteous majority. Without their hapless victims they become like a bully standing alone in the schoolyard, impotently yearning for somebody to punch down on.
