Close Up Shot

The close up shot on 1.20 is very effective because the composition of the shot focuses on 50 Cent's face. Because the background of the cell is plain and green, it gives 50 Cent's face a strong focus from the audience. The shot draws the audience into the main focal point of the shot which is 50 Cent and this enables the audience to read the facial expressions of the character. The shot is so close to the main focal point (50 Cent) that tension will rise within the scene and the audience will wonder what is going on or what is going to happen.
