This is probably the greatest advantage of Raw for these superzooms, since they have not great DR to start with. Using RawTherapee on raw files from Sx30 (courtesy CHDK) has let me pull signicantly more shadow detail and highlight detail vs the OOC JPEG. Since I am keeping the SX40 whether I keep the FZ150 or not, I really hope the CHDK crew works on it soon. I should probably start a "Let's buy Phil a camera" thread on the Canon forum. The FZ150's built-in, thus much faster, raw capability is a real advantage.
