Opening sequence: Seven

Camera angles and shots

When the two detectives were first walking down the busy street in the city the camera is always below the two detectives looking up at them as they walk. This is effective as it shows them in a position of power as they walk.  Rather than being diminished by the imposing buildings surrounding them in the city street

As the detectives  are walking they are being followed with a tracking shot. This shot is deployed to show how busy they are and shows how far they are walking and keeps up with them amongst the hustle and bustle of the city.
