Use Predefined Modes

Many people don't know that most cameras now come with selected modes for taking shots. Eg Landscape, Cloudy Day, Full Sun, Indoors, Night.
Changing the mode of your camera to match your situation can result in better shots, as the camera has a better chance of selecting the shutter speed, flash and other exposure choices for a perfect picture.
Camera makers put a lot of thought into the settings for each of the different modes and tailor the settings to what will work well with their camera. So don't be afraid to use the predefined scene modes of your camera.
