Is there no option to put this cam to ISO 100? DigiCams in that class all do have their grain-problems which increase heavily with raising the ISO-value. I fear, you can't do anything against it on the cameras side. If you want, you may give neatimage a chance. It's a great software to eliminate digicam-grain .. and it's a lot easier than doing it with PS .. with almost the same result or even better, if one lacks the PS-knowledge.
