Is it necessary for photography to be horizontal and vertical?

Under normal circumstances, yes, but there are also special composition methods. For example, when shooting people, you can turn the camera to a certain angle so that the people are on the diagonal of the picture. Composition has certain rules, but it is not completely limited. Some people deliberately break the golden ratio, and the photos they take feel very different.
