manually set the iso and light source helps the most. The artifacts are coming from the auto setting for the iso or shutter speed. You can see the difference on your screen if the colors look wrong first change the light source filter ie daylight cloudy florescent lights vs incandescent lamps. Then change the iso the higher the number the brighter the picts. So in lower light use a higher iso in in brighter lights use a lower outdoors use 100 indoors 200 lower light indoors try 400 I do not think I would really try anything higher unless you are trying to take outside or really dark picts.
