[font color=\'#000000\']Isn't the double frame trick essentially what Fuji does with one of their new sensors? I think it's the SR that has two sets of pixels, one of which is much less sensitive than the other (tucked in the spaces between the bigger pixels). They actually work during the same exposure if I understand it correctly. Of course, you lose some resolution by doing this (you don't cut it in half, because the low sensitivity pixels are much smaller, but you DO lose 30% or so). Highlights record on the small, low sensitivity pixels, while shadows are on the larger, higher sensitivity ones. I think this is what the S3 is supposed to do. I don't know about the noise implications, because the highlights are effectively being captured with digicam sized pixels, but the small pixels are using a VERY low iso (operating two-three stops down from main exposure), and capturing highlights, not noisier shadows.
