Gossip Girl - Cinematography Analysis

The clip begins with an establishing shot to set the scene, giving an idea to the viewer as to where the episode is taking place and an idea as to what may be included.
The camera uses a mid shot of Blair and Chuck towards the beginning of the clip, and cuts between the two before speaking. This allows the viewer to understand the following scene is likely to be focused on the two characters and engages the viewer. The camera then focuses on using a two-shot as the two characters walk towards each other. This creates a dramatic effect with use of camera, music and mise en scene to further engage the audience and cause them to sympathise with the characters. The camera shot deliberately focuses on the two being alone on the bridge together for effect.
A mid shot is used to establish conversation beginning and over the shoulder shots continuously throughout the conversation to empathise with Blair and Chuck. 
Throughout this scene Blair is deliberately dressed in a long red dress, the colour red having connotations of love and hate, which is exactly what the two characters resemble while Chuck is simply wearing a plain and simple outfit. The idea that Blair is dressed very well and Chuck not so much, suggests that Blair is superior for once and in control of the situation, and Chuck simply follows, deliberately contrasting to the norm between the two.
Further along the clip the camera focuses on using close up shots to establish emotion. It is clear to see both characters are distressed and upset,  yet completely in love with eachother and the use of a close up helps further demonstrate this, causing the viewer to feel much more engaged and sympathetic towards Blair and Chuck.
The camera uses upwards panning to first establish what is being given to Chuck and then to focus on Blair's emotion and remorse throughout. The camera then focuses again in a close up of the two characters looking down at the ring and this reinforces the emotion between the two characters.
To close the scene the camera uses a two shot again of the characters standing on the bridge in the position they would be when reciprocating their vowels to one another, this is deliberate positioning for effect. The mid-long shot with Blair and Chuck in it signals the ending to the scene.
