Just a link to a pic I took with a Canon Powershot A620. Nothing done to it, not even levels or sharpening....I wanted toshow something out of camera, as it is.
I quite often find with this camera I hardlyneed to sharpen at all (presumably Canon do it for you),which really helps keep the noise levels low.
