The use of light is vital to improving image quality. Lights can help avoid shadows and create soft features on your face, so turn your face toward the main light source. If you want to be creative, play with light angles by turning your body, but make sure the photo is properly exposed and your face is lit from the front or the side. Besides, avoid taking selfies against the main light source or with overhead lighting. Additionally, natural light possesses a warmth that makes you look like you're glowing (发光)．

　　When taking selfies, angles also matter a lot. Hold the camera away from your face, and try to take photos both horizontally (水平地) and vertically. If not, your face might look bigger than usual. Ideally, the universal selfie angle is 45 degrees above your head. But you should study your face at different angles because finding your best angle requires you having seen all of them.

　　One problem with selfies is that most have distracting backgrounds. You can always do more to show others your best side. Try to simplify the background by taking selfies outdoors or in spacious areas. Document yourself engaging in interesting activities­hiking with family members, visiting landmarks, or working out with friends. At least, you can make the photo appealing by getting rid of your outstretched arm or a background that's too busy.

　　You can also download some photo apps that allow you to adjust the lighting and contrast. Some apps offer useful filters(滤光器), which can change your skin tone and eliminate pimples (粉刺) on your face.
