What is a wide-angle camera?

Wide-angle lens is a photographic lens with shorter focal length, larger viewing angle, longer focal length and smaller viewing angle than standard lens.

Wide-angle lens refers to the angle of a fan angle from the lowest end to the highest end of the camera's illumination range, that is, the angle of the lens, which is actually how big the illumination range is. Generally, the wider the lens angle, the larger the visual range and the smaller the effective visual range. Wide-angle digital camera has short focal length, wide viewing angle and deep scenery, which is suitable for taking photos of large scenes, such as architecture and scenery.

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 cameras) use ordinary wide-angle lenses of 38-35 mm

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

Extended data:

The scenery shot by wide-angle lens is large near and small far, and the perspective effect is exaggerated. The closer the subject is to the camera, the more obvious the exaggeration becomes. Therefore, when taking portraits, people should not be too close to the camera, otherwise it is easy to take deformed photos of "fat nose and mouse ears". Of course, the works of art shot with this effect are excluded, such as The Hand Holding the Vote, which is a very famous photo.

When shooting a building with a wide-angle lens, the lens tilts up or down, which makes it easy for the parallel lines of the building edge contour to shrink or intersect in the distance. Pay attention to choose the contraction point on the center line of the framing picture, otherwise it will easily skew the building image and give people the illusion of collapse.
