Backlight is generally used to outline the outline lines, separating the object or person being photographed from the background, creating a sense of space depth, and the picture effect is not dull and energetic.

Photography is a language, and a good photographic work can be understood by the audience without the need for a photographer to interpret it. When you see a work, your mood at the moment, "invisible new world" may be a kind of emotion, feeling, or a story, thought, realm ... A movie will express a philosophy of life or a social phenomenon, and so will a photo.
Master Alfred Stieglitz of Alfie has a famous saying: When there is light, you can take photos. If you want to find your own "feeling" about photography, you might as well start by feeling the light. When you begin to feel the light, you will find that the light is constantly changing from morning till night.
Your eyes will see that no light for a second is exactly the same. Of course, in these light and shadow worlds, no one or anything is the same, and your heart will feel that every moment in your life is unique and unrepeatable. You will love photography even more, an art that turns an instant into eternity.
Art comes from life. Only by being close to life and feeling life, inspiration will naturally flood in. Memories of the past, expectations of the future, living in the present, there are thousands of ways to express things, and they must be the best.
