Secondly, if your small calendar features some black characters as well as red ones, then you'll note that looking through the *blue* filter turns the red characters (nearly) as black as the black ones... And again, not being a -total- idiot, I'm well aware of that. Just because I limited my comments to how the red filter eliminates the red image, not the blue, does not mean that I'm completely in the dark about everything else. Let me try to be more specific and comprehensive: The red filter eliminates the red image but shows the blue image as dark. The blue filter eliminates the blue image but shows the red image as dark. That's how the damn things work. By 'eliminates' I don't mean that the blue and red don't enter your eyeballs. I mean that the images are lost to your perception, except in certain cases where they can be inferred, for example, the red squares are still framed by the black squares on your checkerboard, so you know they're there, and of course they're red to your eye because the red filter in letting in red light. Quote:which approximates my illustrative example (a.k.a. "concocted experiment"). I'll get back to more on your checkerboard concoction later. I'm building up a case, but need to put it all in order. |
