The lamps and light sources are used for illuminating a film scene.
- The key light is the main source for illumination.
- The fill light alleviates shadows cast by the key light.
- In studio shooting in classical Hollywood cinema, the tree point lighting was customary: in addition to key, fill and back lights.
- Back light illuminated the subject from above or behind, calling for rearrangement of lights for almost every new framing of a scene.
- High key lighting designates a brilliantly lit scene with minimal shadows and a bright and dominant key light.
- In high contrast lighting, there is a considerable contrast between bright lightened shadow.
- Low key lighting involves illumination towards the darker end of the scale and a less bright key light, producing a scene with a good deal of shadows.
- Arc lights which was provided a strong and intense light created by an electrical current jumping between two carbon rods- hence the term 'arc'.
- Alongside development in film stock and to match filmmakers' ambitions to work in location, the use of tungsten halogen lighting became established.
- Fay lights: set of four, eight or even sixteen lights built into a single high-power light panel.
- Cold lighting is based on florescent light sources. the original barrier to the use of this type of light was twofold: cold lighting as not powerful enough for illuminating and more significantly, its colour spectrum is biased towards the green or violet and produces images with a green or purple tint.
