What should I pay attention to when comparing medium format film photography with 35mm film?

Main differences between medium format film camera and 35mm camera and problems needing attention;

From the composition point of view: compared with 35mm film, the frame of medium format film is more square. In addition to 60X60 and 120 films, there are 60X45 and 60X70 frames, and their composition aspect ratio is smaller, which is not as big as 36X24mm of 35mm. The golden section should be used more in the composition of the picture. Of course, when shooting still life, the central area can also be used as the main part of the picture. Diagonal composition should be paid attention to as much as possible, because in most cases, the visual impact of the picture near the square will not be too great.

For exposure: the two films are only related to the film type, not to the film size.

In the use of the camera: 135' s camera is small and flexible to operate. Compared with the medium format camera, it is not very convenient, but because it is "big and heavy", it is more stable and takes clearer photos (referring to the film with the same magnification, regardless of the imaging coefficient of the lens).
