The focus of photographic language

Focusing is also an inevitable technical link in shooting activities. The focal length of the lens controls the clarity of the imaging of the subject, and the proper combination of focal length and aperture often produces surprising results. For example, spring returns to the earth and everything recovers. If we focus on the tender leaves of willow branches, people, especially those with umbrellas, will be blurred into colorful blocks with large apertures, and the clear tender leaves and colorful backgrounds will form the scene of spring.
