The camera settings in which you make photographs of people, event, pets or a landscape are important because they add to the viewer's understanding of your subject.

The room in which a person lives or works, their house, the city street they walk, the place in which they seek relaxation—whatever it is, the setting provides information about people and tells us something about their lives.

Seek balance between the subject and environment. Include enough of the settings to aid your image, but not so much that the subject is lost in it.
