Noise Reduction

We measured relatively high levels of noise in the D20's photos, but Canon's clever noise reduction software keeps shots looking good through ISO 1600, if a bit smooth. The noise-to-signal ratio climbs pretty consistently throughout the entire range, starting at a reasonable 0.83% at the base ISO, and topping out at 2.17% at ISO 3200 (which we wouldn't recommend using). More on how we test noise.

ISO Options

The ISO range stretches from ISO 100 to 3200 in full stops. Users can set the sensitivity, or leave it up to the camera (which seems to cap the sensitivity at ISO 1600—a smart move). In Low Light mode, the range can extend up to ISO 6400 if the camera deems it necessary, but it's recorded at a much lower resolution.
