lighting

key light: this is one of the main 3 lights on a movie set. this is usually the brightest of the 3.

 

back light: this is another of the 3 lights on a movie set. this is behind the actor to create an outline/silhouette of the actor.

 

filler light: this is the last of the 3 lights on a movie set. this is usually put to the side of the actor. this is used to create shadows.

 

under lighting: this is when the source of the light is underneath the subject. this type of lighting is usually in thrillers/horrors to give intimidating scary lighting to the actor.

 

top lighting: this is when the light is above the actor. this makes the actor look more younger.

 

low key lighting: this is when the back and key lights are used to create a contrast between dark and light.

 

high key lighting: this is when more filler lights are being used, this creates a more realistic lighting.
