Camerawork Analysis

1) Three camera shots:

The opening long shot shows the boy riding his bike in a corridor in a hospital. We are following the child and can confirm see his is young and see he is a child.

The extreme close-up we can see the child's expression and emotions. He is startled but also puzzled at the sight of the two twins in front of his face.   
We can see him breathing fast which make the audience feel that the twins are supernatural and unorthodox.

The over-the-shoulder shot at 0.44 shows the child looking at the twins and recognises who they are and how the were massacre in the same corridor it is also a medium close-up which allows the audience to see the monochromatic faces of the twins.

2) Two camera angles:

The unusual angle shows how they are supernatural and creates suspense and surprise the audience and show how fearful this twins must be.

Also it is low shot shows the power of the two twins and have dominance of the little boy. It also makes sense as the little boy is on a bike that is low.

3) Analyse the camera movement:

The camera movement in the beginning of the scene is slow, steady and getting further away from the child. The atmosphere is calm as the child is riding around the corner. The smooth track or dolly shot then becomes faster building tension (0.16-0.23) which makes the audience feel like he is riding faster.

Then the camera zooms in a out of the twins deceased on the floor and goes into the twin emotionless faces. The makes the audience feel sympathy for the little boy as he witness the the twins dying and reappearing out of no where.

Also the camera abruptly stops and becomes hand held and shaky so it creates a unnerving atmosphere and show the audience that it is extraordinary
