The way I'd do it in Fireworks is to copy the image and mask out all the pixels in one with the brightness >20 and in the other with the brightness <=20. Then I'd apply the appropriate blend mode to each image. Since the pixels in each that got masked out would be transparent, when the two images are overlaid, you should get the desired effect. Not sure if you could duplicate this in Flex, but maybe hearing another perspective on the problem would help. HTH; Amy
