Each photography is a story. A piece of information shared with the person taking it and the person viewing it. Low angle is a way to make your subject more powerful, more impactful. Typically, we place the camera below eye line, often placed directly above a person feet.
We see low angle shots all the time in movies. They help us identify who has all the power in the scene.
