What does the border of SLR camera mean?

The frame of a SLR camera refers to the size of the picture that the camera can shoot. Different from digital cameras, SLR cameras use film, so the border is directly related to the size of the film. Common frames are Quan Huafu (36×24mm), APS-C frame (about 24× 16mm) and medium frame (about 56×45mm). Different frames will affect the perspective and clarity of photos, so they are suitable for different shooting scenes and needs.

Full-frame camera can shoot a more realistic visual experience because of its large frame, which is more suitable for shooting distant scenes or big scenes. At the same time, the image quality of full-frame camera is relatively good because of the uniform pixel distribution. APS-C format camera is more suitable for daily shooting, such as portrait or street view. This kind of camera needs to stand farther when shooting because of its small frame, in order to get a better picture.

Because the middle frame is larger, it has great advantages in shooting quality and detail. Medium format cameras are expensive and suitable for professional photographers. However, they are essential for displaying works and publishing, and they play a very important role in the commercial field. In short, different frames are suitable for different scenes and needs, and choosing the camera that suits you is a learning process that photographers must go through.
