How are shadows casted?
Introduction. Cast and attached shadows are a fundamental presence in natural visual scenes. Cast shadows, caused by the blockage of light from a light source by the object, or part of the object, project onto a surface (extrinsic cast shadow), or onto a part of the object itself (intrinsic cast shadow).
What is the importance of shadows in drawing?

Lightly draw the shadow line; it has a slight curve to it.
How do shadows work in art?
The characteristics of the cast shadow are dependent on the intensity of the light source. A hard light will produce a cast shadow with a sharp edge, a soft light will produce a cast shadow with a more blurry edge. The longer the cast shadow is from the object, the softer the edge of the shadow becomes.
