That point and shoot camera by default focuses on a tiny point on the center of the frame by default when setting the white balance, thus it will have poor results depending on what you aim at. you can either change it, or do the right thing and install CHDK on the camera and shoot in camera raw. not only do you get significantly better image quality (the camera does a low quality fast jpeg processing to keep a decent frame rate, but that comes at the cost of fine details, noise, and dynamic range.
