Final answer:
Foreshortening is the technique of visually compressing a prop or model in photography or art to make it appear larger than its actual size to create perspective.
Step-by-step explanation:
The technique of making a prop or model appear larger than it really is within a shot by compressing it is known as foreshortening. Foreshortening is a method of creating perspective in visual art, where the size of an object decreases in relation to its distance from the viewer, to give a sense of depth. This technique exaggerates the part of the object that is closer to the viewer, making it appear larger and thereby creating a realistic depiction of spatial depth.
When cameras or artists employ this method, they adjust the distances and angles to create the illusion that objects stretch into space. This effect can make certain elements within an image appear more prominent, even if their real-world size is smaller. This is not to be confused with zooming, which enlarges the entire image, or scaling, which uniformly changes the size of an object.
