At ISO 400 the difference is much more pronounced, with the SD450 image having lost lots of fine detail (and contrast) due to very heavy noise reduction. The Panasonic LZ2 fares slightly better by producing a sharper-looking image (with a touch more detail), though again, noise reduction (with Panasonic's trademark 'watercolor' look) and fairly aggressive sharpening has taken its toll. Still, it doesn't take an imaging expert to see which of these ISO 400 results would produce the sharper, more attractive print!
Again, it is worth noting that - despite both cameras being set to 'ISO 400', the Canon is clearly more sensitive (around 2/3 stop), which means the noise difference is probably less than these shots would indicate.
