Session 4 was a Master Class given by Magnus, a Cinematographer. Magnus demonstrated various methods of creating atmosphere using lights, lenses and shots. The filmmakers got a chance to experiment with the lights, creating both soft and harsh lighting. They also had a play with the differnet lenses and saw how this can alter the mood of a scene. The filmmakers watched a clip of Magnus's film, when it was paused they guessed what kind of shot was being used and why; for example, hand held to create a rawness. The filmmakers then got to see a tracking shot in action.
