Lighting

Lighting in used in film are used to show emotion in characters or the mood of the scene. There are different types of lighting to create this effect such as: 

• Key light - This light is the main light which is mainly the brightest.
• Back light - This does the opposite of the key light, and it gives the effect of a character looking rounded.
• Filler light - This light deminishes the shadows that are created by the filler and the back light. 

The Key light can be positioned to create different effects like:

• Back lighting - This light is shot from behing the character to create a silhouette effect on them.
• Under lighting - This light is shot from beneath the character to create a mysterious look.
• Top lighting  - This light is shot from above the character to highlight their features.

 There is also Low-key and High-key lighting:

• Low-key lighting is the use of only the key and back lights to create a contrast between light and dark areas to create distinc shadows.
• High-key lighting is the use of more filler lighting to make a more normal and realistic look.
