It's important to be conscious of the decision-making when choosing the lighting for shooting in a particular setting for both practical and aesthetic reasons. Lighting should convey a pre-determined tone or mood in a way that supplements the film content without being distracting.

The three point system--

key light - the main light, should generally illuminate both eyes of subject and give the face definition. Positioning the key light slightly to one side of the prevents giving the subject a flat, featureless effect.

fill light - fills in shadows and provides a softer light than the key light. A, important tool in interviews because a well-lit subject appears more engaging and approachable.

back light - gives definition to outlines and serves to separate subject from background. Catches the jawline, brightens the head and shoulders, and creates a warm and friendly film environment.

--is a standard guideline for lighting in film. It is important to note that these terms are not related to the lighting products themselves, but to whatever use a lighting product is being put towards.

Additional ways to manipulate light include:

using warm/cool toned lights to find white light balance

underneath lighting - can create sense of distrust or dislike toward subject

overhead lighting - can be threatening, is reminiscent of hostile interrogations 

Farnell lights - to create less ragged shadows than open-faced lights

light diffusion via mesh screens or light refracting surfaces
