Carefully look at the diagram titled "Mosaic Filter: Each Pixel - 1 Color" (which really should say "Each Sensor" not pixel) and note that the blue filter blocks red and green, that the green filter blocks red and blue and that the red filter blocks green and blue. OK, that works for me. Now go down to "Mosaic Filter vs. Foveon X3" and they show a similar diagram, showing how Mosaic filters block light...but magically, in their sensor diagram below that, they show a blue filter, that passes both red and green...right through, as well as a green filter that passes red. I'm not clear on how this works...and that is obviously their key to making this work. I'm all for this type of 3d technology, since I have been designing digital imaging equipment for over 25 years, this 3d approach is how most anyone in the field believe it should be done anyway, the concept is hardly new, and has been around a lot longer than Foveon...but it's the implementation that is important, not the concept. As I said, I do like that they separate out the difference between sensor and pixel, something that has been a peeve of mine for years ;-) Austin ---------------------------------------------------------------------------------------- Unsubscribe by mail to [EMAIL PROTECTED], with 'unsubscribe filmscanners' or 'unsubscribe filmscanners_digest' (as appropriate) in the message title or body
