What's the difference between a wide-angle camera and an ordinary camera?

1. Wide-angle camera: It is a camera with a viewing angle above 120 degrees.

2. Ordinary camera: refers to the camera with HD 1080P or HD960P or HD720P.

Second, the use is different.

1. Wide-angle camera: realize seamless monitoring and realize new monitoring applications, which are applied in various fields, including prisons, government agencies, banks, social security, public places and cultural places.

2. Ordinary camera: it is used to obtain high-quality and high-definition image information, and it is used in traffic, inspection, withdrawal, supermarkets, kindergartens and other fields.

Skills of using wide-angle lens:

1, wide viewing angle, covering a wide range of scenery. The so-called wide viewing angle range means that at the same viewing point (the distance from the subject is constant), the scene is viewed with wide-angle, standard and telephoto lenses with three different focal lengths. As a result, the former shoots more up, down, left and right scenes than the latter. When the photographer has no retreat, it is difficult to take a complete picture (such as taking a group photo) with a standard lens of 50 mm ), using a wide-angle lens can easily solve the problem.

2, can emphasize the prospect, highlight the contrast between far and near. This is another important performance of wide-angle lens. The so-called emphasis on foreground and far-near contrast means that wide-angle lens can emphasize far-near contrast more than other lenses. In other words, the photos taken with wide-angle lens are closer and farther, which makes people feel that the distance has been widened and has a strong perspective effect in the depth direction. Especially when shooting with a super wide-angle lens with short focal length, the effect of being near big and far small is particularly remarkable.

3, you can exaggerate the deformation. Use a wide-angle lens to deform the subject moderately and take some very inconspicuous scenes that people turn a blind eye to. The use of wide-angle lenses for exaggerated deformation should be based on the needs of the subject matter, less but more precise. No matter whether the theme is necessary or not, it is not worthwhile to abuse the exaggerated deformation of wide-angle lens and blindly pursue the bizarre effect in form.
