If the semi-dark area is lit primarily by daylight, then the fixed "sunshine" setting will give good results. If you are shooting in artificial light, then the "light bulb" setting will be accurate if you are sure there are no fluorescent tubes contributing. The most accurate method is to perform a white balance by pointing the camera at a white sheet of paper in the area you are filming and pressing the white balance button. Don't forget to repeat the white balance when you change locations. In most conditions, the camera will work pretty well in auto white balance anyway, so if the above freaks you out, then auto could be the answer!(posted 8455 days ago)Gareth
