Camera angles- A point of view shot

This shot, also known as a POV shot is a short film scene which shows what the character is looking at through the camera. It is usually used between scenes - a character looking at something and then their reaction. This technique is one of the foundations of film editing. The technique is commonly used in horror films where we are placed in the position of the killer who is sneaking up on a victim. Sometimes this shot is taken over the shoulder of the character, the POV can also be shared by two or more characters. Here is a short film of someone using the point of view shot.
