Image of 'Sam' from the Maltease Falcon, which the Silhouette of the falcon and sam projected on the wall

 

A two-shot of a male and a female facing each other. none of their features are highlighted just the Silhouette's of the figures stand out in the bright smoke.

Again a female figure signaling a car to stop in the night, only her black outline is visable on the brightly lit road and field with the light source in the centre of the frame.

  

This image is a good example of how smoke can look with a dark background with light shon onto it.

Another theme that is associated with film noir lighting is that of the slanted blinds. They project light and shadow onto charaters and objects suggesting they have both a dark & a light side to them. 

Again another lighting effect of film noir. this dark room makes this charters figure seem really authoritive due to the camera angle and the use of the light casing shadows from the figure.

One more example of a femme fatale with the slanted blind effect.

Here is a film poster from the classic film noir of the 'Maltese Falcon' which uses many conventions of Film Noir
