Genre research ( Horror )

Camera-

Angles-

Long shots are sometimes used to establish location, since these films tend to be confined in one space. Birds eye view conveys a feeling of helplessness

Movement-

The camera will sometimes follow the subject either literally or 'following' scene to scene.

Costumes-

 Costumes are usually dark, as not to distract from unsettling environments.

Lighting-

Lighting usually stays in the darker range.

Acting-

Actors are usually lesser known, for the sake of making it easier for the audience to project on to the characters emotionally. The acting is meant to be taken seriously, and make the viewer distressed.

Makeup-

Makeup of the protagonists are kept simple, but the antagonist may have exaggerated makeup to play into the fear factor.

Props-

Unless plot relevant props are also kept simple. Often times weapons are used, pistols or some sort of gun usually.

Set-

Settings are usually confined to play into a trapped atmosphere, or several locations that play into a helpless inescapable feeling coming from the antagonists.

Editing-

If the antagonist is supernatural, it will often make unnatural edited noses.

Sound-

Ties in with the potential antagonist sound editing. It tends to be quiet during tense moments, jump-scares might have sharp instruments play suddenly
