Wide-angle lenses expand space. If the lens's angle is wide enough, it even noticeably distorts space. Horror films have found many applications, both aesthetic and pragmatic, for wide-angle lenses. Among its uses, a wide-angle lens can...
* Depict the subjective POV of a person who's drugged, drunk, tired, or insane.
* Depict the subjective POV of an unnatural creature (e.g., a ghost, alien, demon).
* Suggest an ominous, alien, or supernatural presence or situation.
* Photograph everthing in small rooms or tight spaces (low-budget films can rarely afford to rent a professional studio in which the camera has enough space to pull back to photograph a scene).
* Expand space so as to suggest a larger setting. (Realtors also use wide-angles lenses for this purpose -- ever notice that houses, lawns, and backyards often look bigger in their Zillow photos than they do at Open House?)
But especially admirable is when a filmmaker achieves more than one aesthetic effect from a wide-angle lens. Such an application may be referred to as being aesthetically efficient.
It is because of its aesthetic efficiency that I admire this shot from "The Concrete Captain," an episode from TV's Ghost Story/Circle of Fear.
In the above scene, a ghost possesses Gene Rowlands, compelling her to come out to the beach. Her husband, played by Stuart Whitman, catches up and tries to bring Rowlands back to the motel. They struggle at the top of some stairs.
The wide-angle lens in this scene achieves two effects.
* First, the lens's distortion of space suggests a supernatural presence (i.e., the ghost possessing Rowlands).
* Second, the lens' expansion of space makes the stairs appear that much higher above the ground. This makes the consequences of falling down those stairs appear that much more dire, thus heightening viewers' tension as they watch Rowlands and Whitman struggle.
