I found the lighting and camera movements in this music video very interesting. the main factors of the lighting which were effective was firstly the the lens flare hitting smoke which created a blue tinted mist which created a mysterious mood and also enhanced the dancers feet movement as the smoke would flow with each move whilst it is swept away. Also the rays of light which beams from behind Chris Brown as he enters the club is used repetitively throughout the duration of the video, this also a great way of making the audience focus on the body movements in the dance as it almost gives a silhouette effect. In terms of camera movement there is a lot tracking in which is used to establish the space of each room and then track in to focus on the choreographed routines, this adds to create the line of symmetry which the dancers formations show.
