Sound and Lighting

There are two types of lighting

1. Low key lighting
2. High key lighting

Low key lighting 

• Slighting silhouetted
• Creates mystery/ draws attention
• Created using only key and back light
• Produces sharp contrast of light and dark areas
• Deep distinct shadows/ silhouettes
• Used in darker films (e.g. horror films)

High key lighting

• More filler lights are used
• Very bright shots
• Creates realistic and natural daylight
• Produces brightly lit sets/ sunny days
• High verisimilitude 
• Used in lighter films (e.g. romcoms)

There are two types of sounds in film

1. Non diegetic 
2. Diegetic

Non diegetic sound

• Sound whose source is not visible
• Often but not always unnatural sounds
• Includes - Narrators commentary
•             -  Sound effects (for dramatic effect)
•             - Atmospheric music

Diegetic sound

• Sound whose source is visible
• Often natural sounds
• High verisimilitude
• Includes - Voices of characters (who are on screen)
•              - Sounds made by objects in frame in the story

Verisimilitude is the appearance of being true or real. Tv shows and films add realism in the there lighting and sound (as well as in other areas) to get verisimilitude.
