The perspective attained when a camera is positioned very low to the ground, looking upwards, creates an unusual and dramatic angle. This technique replicates the view a worm might have, hence its descriptive name. A common example would be photographing a tall building from its base, emphasizing its height and creating a sense of overwhelming scale.
Employing this specific vantage point offers several advantages. It can emphasize the size and power of subjects, introduce a unique artistic interpretation, and distort familiar shapes, leading to visually striking images. Historically, it has been used to convey feelings of insignificance or awe, often found in architectural and urban photography to highlight grandeur and imposing structures.
