Saw II opening sequence starts of with an extreme close up of a light bulb with heavy breathing and noises of the bulb about to explode, this creates tension right at the beginning of the film. The sound used in the opening is non diagetic as we hear echos to establish the scene. Extra diagetic sound is used as the character on the chair starts to scream, this is used to show a more detailed expression of the character and to create more suspence to the audience, the screaming shot is shooted with an extreme close up this also shows detailed expressions. The opening sequence uses a great deal of silence, because silence is a classic code and convention of the thriller genre, it also helps to create suspence and tension.
The lighting used at the begining is High key lishting as we see an extreme close up of a light bulb. The lighting mainly used in this opening sequence is from the light tubes for the set, and this gives better and more effect than natural lighting.

Mis-en-scene- the mis-en-scene at 2:44 shows a close up of the character cutting his eye, this a horror/thriller shot, because it fits more into the horror genre.
