At ISO 800 it's the same story, just more so. The Canon output is undeniably noisy, but it is a more 'honest' representation of the CCD's output, and there is more detail and texture. By comparison the C875's heavy noise reduction is producing a slightly smeary result, with the loss of a lot of fine detail.

Ultimately, however, neither camera is producing output you'd want to use unless you really had to, and the difference is as much a matter of taste as it is of absolute image quality. It is possible, using noise reduction software, to make the Canon output look like the Kodak, but not the other way round (you can't 'undo' high noise reduction). For the typical first-time digital user that the C875 is aimed at the ISO 800 output will produce an acceptable postcard-sized print of subjects (such as low light portraits) where fine, low contrast detail and texture isn't hugely important.
