Camera Angles: High Angle

Most of the time you want to shoot people at their eye level. 

It makes the camera a neutral observer. Shooting down towards your subject gives the impression that they are submissive. This is called a "High Angle" shot.

High angle shots also make the figure or object seem vulnerable or powerless.

High angle shots are usually used in film to make the moment more dramatic or if there is someone at a high level that the character below is talking to.
