Bryan Norton, The professor at the New York Academy of filmmaking:
The Snapshot in itself is the most important tiniest technical matters relevant to the scenario industry, so it has to be made in a brilliant, technical and psychological way, we will discuss here the most important factors for the footage of a image to be taken, which is relevant to the psychological state of the viewer , or what we call a psychological scenes. Let us discuss how to be influential to the point of view of mental imagery viewer and the landscape itself.
Lets apply the following example:
If we put the camera to an eye-level, often draw this angle gives the figures within the picture, or their standing before the equal, and strength, without the superiority of one over the other.

If we have the camera above the eye-level, and we look to the bottom, in the sense that the camera was the highest, shall be subject to photography, this shot shows the vulnerability of the person the subject of photography.
But to make the camera above the eye-level and we look to the top, it gives the status of power and control, or that the personal control of the scene.
This shows that we can use the footage as a worthy scene, and in the manner that serves the delivery of the idea of the scene, and can be considered as a suggestive shot, or to provide in a clear and obvious image view.
Often this decision is usually taken in the script, which separates the grounds of the scene here, and exit options become clearer on how it aims to tell the story is visible or not.
You could use the previous three images in any film project that you would like to direct, to consolidate.
