![]() Size does matter as far as casting shadows goes. The area light is often used to cast soft shadows in a scene. Penumbra is formed by overlapping part of one shadow and then a part of an illuminated region outside of the other shadow. The penumbra region features a light source that is partially visible. The lighter shadow region in a shadow is called the penumbra. The distance of the light from an object determines the softness of the shadows. This effect produces smooth shadowed regions that are not parallel to the light source’s line segment. Soft shadows are created when the light source if bigger than the subject. But when used improperly, it could give a stark, unrealistic look and feel to a scene. ![]() When applied properly, hard shadows add dimension to an image. However, a computer graphic software has several algorithms that enable artists to compute hard shadows in real time.ĭirectional, point, spotlights, and other non-extended light sources are often used to create hard shadows. One thing to keep in mind when creating hard shadows, even the sun, which is the planet’s main source of light, does not create hard shadows. It’s produced by overlapping the shadows. This type of shadow occurs when the size of the light source is smaller compared to the size of the object. The dark region of a shadow is called the umbra. This shadow effect features sharp boundaries and fully shadowed areas. Hard shadows refer to the defined edges of the shadows. Shadows become softer or lighter as the object is drawn further away from a light source. The general rule is that the darker the shadow, the brighter the light source. The distance between objects could also influence the hardness or softness of the shadows as well as the intensity of the light. The shadows that objects cast in a scene could be described as either soft or hard. Photo Credit: Types of Shadows: Soft and Hard Shadows
