2) Bright sun can create unattractive deep facial shadows. Eliminate the shadows by using your flash to lighten your face.
3) Center stage is a great place for a performer to be. However, the middle of your picture is not the best place for your subject. Bring your picture to life by moving your subject away from the middle of your picture.
4) If your subject is not in the center of the picture, you need to lock the focus to create a sharp picture. Most auto-focus cameras focus on whatever is in the center of the picture. But to improve pictures, you will often want to move the subject away from the center of the picture. If you don't want a blurred picture, you'll need to first lock the focus with the subject in the middle and then recompose the picture so the subject is away from the middle.
5) In taking great photos of landscapes, you can use diagonal lines to help you draw the attention of the viewer in to your focal point. Keep in mind that diagonal lines in your photo can be lines of trees or a fence or a flowing river. Positioning it so it may appear diagonal in your photo can make your photo a good one too.
