Film Noir films have a main setting in more rural areas. This is because there are lots of different things that can be used to create shadows that have high contrast with the backdrop. The stronger the colour contrast is, the more powerful the message is.
It is always assumed that Film Noirs are filmed in black and white, but this a stererotypical opinion that has only stuck because the most famous film noir films were filmed when colour filming was expensive.
Flashbacks and first person voice overs create
unpredictable and exciting film. Plot devices such as the protagonist
suffering from amnesia were also very common. This is because the viewer feels uneasy, as they cannot be certain what is going on.
Film noir storylines are expressed by the use of low-key lighting, juxtaposition, skewed camera
angles, circling cigarette smoke and dull compositions. Typical cinematography settings
include Venetian blinds, vertical bars, dark streets, flashing neon lights and generally
gloomy places.
