Which type of light creates sharp and distinct shadows?

Hard light is the type of light that creates sharp and distinct shadows due to its direct and concentrated nature. When a light source is strong and focused, it produces pronounced contrast between the illuminated areas and the shadows. This is because hard light has a small diffusion area, resulting in well-defined edges around the shadows.

In contrast, diffuse light, soft light, and ambient light all tend to soften the edges of shadows, making them less distinct. Diffuse light scatters as it reaches the subject, softening the overall illumination and producing gradual transitions between light and shadow. Soft light, similar in effect to diffuse light, comes from larger or more dispersed sources that reduce sharp contrasts. Ambient light refers to the general illumination that is present in a scene, filling in shadows and further diminishing their definition. Thus, hard light is specifically associated with clear shadows, making it the correct answer to the question.
