Does anyone know why the file sizes of the sample Z750 pictures are substantially larger than those of the Canon SD500? Would it be a difference in the jpeg compression, or some other cause?

The SD500 images have been said to contain less noise than the EX-Z750 images. Either this is because the sensor is better or Canon "hide" the noise by blurring slightly.

If this is true then the SD500 images should compress better than the "noisy" Casio images. Even though the compression ratio might be the same for both cameras, the Canon images with less complexity due to reduced noise would be smaller.

Of course I could be talking rubbish, but I think I'm probably right.

I know that higher ISO (and more noisy) images on my EOS require more space to store.
