What does it mean to shoot wide-angle with a mobile phone?

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer distance and smaller viewing angle than standard lens. In photography creation, shooting with a wide-angle lens can achieve the following effects:

1, which can increase the sense of space in road photography.

2, the depth of field is long, which can ensure that the scenes before and after the subject are clearly reproduced on the screen. Therefore, the vast majority of modern pocket automatic cameras (commonly known as fool cameras) use ordinary wide-angle lenses of 38-35 mm

3, the lens covers a large area, and the shooting range is wide.

4. The scene shot at the same shooting distance is smaller than the scene image shot with the standard lens.

5. Perspective distortion and image distortion are easy to appear in the picture. The shorter the focal length of the lens and the closer the shooting distance, the more obvious this defect is.
