Shot Composition- life on mars

When Sam approaches the police station we see a framing, this sets the scene. Sam is framed by a scruffy police station and cars etc around him. While this is happening we also see a deep focus while Sam is walking into the police station, this is chosen so the audience can see what kind of area he is in and what the location is like. Inside the police station we see a shallow focus while Sam is on the phone, this tells us that what Sam is doing is very important and by putting everybody in the background blurry, it focuses our attention onto Sam. The next scene we see inside a mortuary, this scene is framed by four walls with two windows, the only light coming into the room is sunlight, this effects this scene as it tells us that it is very mysterious and that it isn’t going to be very happy place due to the amount of light and no colour on the walls.While Sam is in the canteen there is a shallow focus this again makes us focus on the emotions from Sam and tells us that he is very confused.A deep focus is used outside the police station while Sam and his women friend are talking this emphasises how big the building is and how little they are compared to it. The next shot composition used is a shallow focus, this happens while Sam is looking into a shop window which he used to go there as a child. This shot was used as it is quite an important scene as Sam is remembering things from the past.
