What are the narrative advantages of long shots? Can you take the "rear window" as an example?

It seems that the landlord asked for a long lens, not a long focal length lens.

Just a brief talk about the future.

The narrative advantage of long lens is the unity of time and space, which has a sense of realism and participation for the audience.

Take the opening of the back window as an example, it is such a long shot that makes everyone participate in real life and gives everyone the most authentic experience. The lens swept one by one, condensing that time and space. If other shooting methods are adopted, it is easy for the audience to skip the details of the relevant description, resulting in the ineffectiveness of the film narrative.

What about the long focal length lens? ...

Compress the space and highlight the main body. ..

Living in a building should be hopeless, hehe.
