What is the use of wide angle? What kind of photos do I have to use?

Generally, the focal length of a wide-angle lens is 38-24 mm and the viewing angle is 60-84 degrees. The ultra wide-angle lens has a focal length of 20- 13 mm and a viewing angle of 94- 1 18 degrees.

Because the wide-angle lens has a short focal length and a large viewing angle, it can shoot a large area of scenery in a short shooting distance. Therefore, it is widely used to shoot large-scale landscape photography. In photography creation, shooting with a wide-angle lens can achieve the following effects:

First, it can increase the sense of spatial depth of photographic images.

Second, the depth of field is long, which can ensure that the scene before and after the subject can be clearly reproduced on the screen. Therefore, the vast majority of modern pocket automatic cameras (commonly known as fool photography

Machine) adopts 38-35 mm ordinary wide-angle lens.

Third, the lens covers a large area and shoots a wide range of scenery.

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

Fifth, 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.
