Shading is used in drawing for depicting different levels of darkness. Applying more densely with a darker shade for darker areas and less densely with a lighter shade for lighter areas is the basic idea.
However, there are some details that you should know. For instance, Shading has five elements. The five elements of shading are:
Cast shadow: It is the darkest part of your drawing because in this part light is completely blocked. Draw this area as black as possible.
Shadow edge: This shading is also known as turning shadow. This area corresponds to a dark grey tone.
Halftone: This is the true color of your object. This area of a drawing is not affected by light.
Reflected light: This shading element is lighter compared to other shadows. But this will still be seen on the darker side of the object. The reflected light is always seen on the edges, rims, or lip of an object.
Full light: This is the area that receives the most light and the tones fade gently into the white of the paper.
