What is a wide-angle lens? Wide angle lens, also known as short focus lens, is a lens with a field angle greater than 60 °; For the zoom lens on the camera, the focal length is less than 25mm

1/ Picture Modeling Characteristics of Wide angle Lens

1. Wide angle of view: the angle of view of wide-angle lens is generally wider than the normal angle of view of people. Generally, the angle of view of optical angle lens is wider than 60 °

2. Large depth of field: it can not only contain scenes with a wider field of view, but also show more profound scenes in depth.

3. The picture includes a wide range of scenes: the wide-angle lens not only has a wide field of view angle, but also has a wide range of depth of field, so it can incorporate most of the scenes in the vertical and horizontal directions in front of the lens into the picture, presenting a picture with a wide field of vision and many scenes, and has a stronger ability to express space.

4. Wide angle lens has distorted image: the closer the camera is to the object, the more obvious the deformation and exaggeration effect will be;

5. The wide-angle lens has two important characteristics when representing moving objects: it is weak in the sense of motion for horizontally moving objects, and the farther away the object is, the weaker it is; It has a strong sense of motion for objects moving longitudinally, and the farther the object is, the stronger it is.

6. Wide angle lens is easy to shoot on shoulder, and the picture is easy to be stable and clear

2/ Function of wide-angle lens

1. It is conducive to displaying a wide range of scenery at close range

2. Wide angle lens is suitable for showing the main body of the picture and its environment

3. Use the characteristics of wide-angle lens depth of field to perform multi-level representation of objects, and the capacity and information content of the home screen

4. Use the wide-angle lens to approach the subject at close range and complete the snapping

5. The exaggerated deformation and distorted image of its line perspective form a special expression significance

6. At the same time, it is conducive to maintaining a stable picture of mobile camera
