When the size of the light source decreases relative to the subject, the resulting shadows become sharper. This occurs because a smaller light source produces more defined edges to the shadow. When light is diffused through a larger source, it creates a softer transition between light and shadow, leading to a more gradual effect. In contrast, as the light source gets smaller, the shadows produced lack this diffusion and thus exhibit a more abrupt delineation, resulting in sharper edges and well-defined shapes. This principle is crucial in photography, as it impacts the mood and texture of the image through shadow play. The sharper shadows can suggest a more dramatic effect, enhancing the three-dimensionality of the subject.
