What are the three lens angles? What are their characteristics or functions?

The angle formed between the camera lens and the horizontal plane of the object is called the lens angle. People generally divide the lens angles into three types, namely, head-up lens, overlooking lens and looking up lens. Head-up lens refers to a lens that keeps basically the same level as the subject. This kind of lens is close to the normal viewing angle and the picture effect is also close to the normal visual effect. Overlooking the lens means that the lens is below the horizontal angle and shot from top to bottom. This kind of lens has the following basic characteristics: making the subject feel depressed, making the audience feel condescending, showing a relatively open scene and space environment, showing moving lines from a specific angle, compressing and deforming the image and producing special effects. Look-up lens refers to a lens shot from bottom to top at a higher angle than the horizontal angle. This kind of lens exaggerates the volume of the image, makes the subject taller and more dignified, gives the audience a sense of oppression or reverence, and can also be used to create sadness and reverence.

Efficient. Sometimes looking up at the camera is also used to imitate the child's perspective.
