Numerous shots create a sequence, just as a combination of letters make up a word.
There are numerous types shots/angels. I would like to explore some of them, to see when and why a director would use them.
1] Establishing shot
This shot can also be called an extreme long shot. Such a shot is used to establish the area, allowing the audience to become acquainted with the area the scene is set in.
2] Long shot
This shot allows the audience to see a life size image of the character. Such a shot can be used to introduce a character. A long shot can also be used to juxtapose a character with the background, allowing the audience to uncover the relationship the character has with the scenery.
3] Medium shot
A mid shot focuses on the character from the shoulders upwards. This shot can be used to put the focus on the character, whilst still keeping his surroundings within view.
4] Close up
A close focuses on the character face. This shot allows the audience to see the characters facial expression in great detail. Such a shot can be used to reveal the characters emotions.
5] Extreme close up
An extreme close up is an unnatural shot, as it magnifies an area beyond what a human can experience in reality. Such a shot can used to place great emphasis on a given area.
6] Eye level
Is a shot taken at the characters eye level. Such a shot can be used to make the audience believe they are observing a scene at a natural eye level.
7] POV
This shot allows the audience to experience things through the characters eyes, making them closer to the character.

8] Over the shoulder
Shows a scene from behind a characters shoulder. This allows the audience to see what the character is looking, without actually bonding with the character. Such a shot can be used on characters the director does not want the audience to bond with.

9] Low angle
Low angle shot can be used to capture a character below his or hers eye level. This will force the audience to look up to him, making the character allot bigger and dominate.
10] High angle
High angle shot can be used to capture a character above his or hers eye level. This will force the audience to look down on the character, like how an adult looks down on a child. This makes the character look smaller, less significant and inferior.
