S100 ISO 6400 - not bad
Now that I've shipped my S100 back to Canon to repair the lens problem, I was looking over some past tests and found this ISO 6400 photo, shot in RAW and converted in DPP + Noiseware and also converted in DxO using its default settings. The DxO version was noticeably better, so here it is. I'd call the result very good indeed for a small-sensor camera.
Full frame reduced to 1200 pixels wide.
