3. How to show the size of the subject

It is difficult to directly judge the actual size of an object from photographic works. The vast sea may be just a horizontal line on the screen, while smaller objects, even objects invisible to the naked eye, can occupy a large area on the screen. At this time, it can be expressed by contrast. On the one hand, the actual size of the object can be known by comparison; On the other hand, we can express certain thoughts and feelings through exaggeration and deformation.

In order to truly show the size of the subject, it is necessary to have a companion as a reference in shooting. Generally speaking, people are familiar with and know the size of objects in daily life as comparison objects. This not only highlights the subject, but also makes the audience impressed by the actual size of the subject.

Photographers should arrange the position of the horizon reasonably when shooting. Generally, when shooting grassland and other scenery, the horizon is arranged in one third of the picture. In addition, when shooting seascapes, the position of the horizon determines the meaning of the picture. If the horizon is in the lower third of the picture, it reflects the distance of the sea; If it is in the last third, it shows the broad feelings of going to sea.
