Which term describes the effect achieved by placing the camera upwards at the subject?

The term that describes the effect achieved by placing the camera upwards at the subject is indeed low angle. This technique involves positioning the camera below the subject and pointing it upwards, which often has the effect of making the subject appear larger, more imposing, or more powerful. It can convey a sense of dominance or authority, depending on the context in which it is used. Filmmakers and photographers utilize this technique to manipulate the viewer's perception of the subject, influencing how the audience feels about the character or object being filmed.

High angle would suggest a view looking down on a subject, which would have the opposite effect of diminishing the perceived power of that subject. Eye level refers to placing the camera at the subject's eye level, offering a neutral perspective without altering the viewer's perception of power dynamics. Bird's eye view indicates a viewpoint directly overhead, typically used to provide an overview of a scene. Each of these alternatives serves a different purpose in visual storytelling compared to the distinct effects created by using a low angle shot.
