Different camera shots can be used to represent different things. For example an extreme close up(XCU) could be used to highlight a certain emotion or to make it clear to the audience that something has happend for example if in a film you wanted to the highlight the fact that the character could hear something unusual, you could do an extreme close up shot of thier ear. A medium close up would most likely be used if you were filming people having a conversation.

Different camera angles and shots can be used for effect in certain clips. For example a point of view shot can be used to increase the audiences emotional attachment to the characters which are on screen. The audience will see exactly what the character sees, so it makes them feel more as if they are actually at the scene.

A dramatic angle shot adds impact to the scene , if it is filmed from a low angle this will highlight how big or powerful somehting is and if it is filmed from a high angle it could represent how small something is and seem as if the audience is looking down on them. For example if you wanted to show how small everything looked from the top of a high building you would use this shot.

A pan shot is used to look across a wide scene as it based on the horizontal movement of the camera. This can be used in a clip to follow a character as they move around.

A tilt shot is the vertical movement of the camera, it could be used to look over tall objects such as a high rise buidling.
