Shading is primarily used to create the illusion of depth and form in a drawing by varying the darkness and lightness of different areas.

Cross-hatching is a shading technique that involves creating a series of parallel lines that intersect each other at various angles, creating a textured effect.

Blending is the technique of gradually transitioning from one shade or tone to another in a drawing, creating a smooth and continuous effect.

Stippling is a shading technique that involves creating a series of short, closely spaced dots or lines to create a textured effect.

Smudging is the technique of using a soft tool to blend and soften the edges of shading, creating a smooth and hazy effect.

Scribbling is a hatching technique that involves creating a series of short, curved lines that overlap and intersect, creating a textured effect.

Scumbling is the technique of creating a series of random, irregular lines or marks to create a textured effect, often used to create a sense of depth or atmosphere.

Hatching is a shading technique that involves creating a series of long, continuous lines that are parallel or at an angle to each other, creating a textured effect.

Linework is the technique of using a hard tool to create sharp, defined lines and edges in a drawing, often used to outline forms and create a sense of structure.

Stippling is a shading technique that involves creating a series of small, circular marks to create a textured effect, often used to create a sense of depth or atmosphere.

Mixed Media is the technique of using a combination of shading and hatching techniques to create a variety of textures and effects in a drawing, allowing for a wide range of artistic expression.

Cross-hatching is a shading technique that involves creating a series of short, straight lines that are perpendicular to each other, creating a textured effect.

Smudging is the technique of using a soft tool to blend and soften the edges of hatching, creating a smooth and hazy effect.

Scribbling is a shading technique that involves creating a series of long, curved lines that overlap and intersect, creating a textured effect.

Chiaroscuro is the technique of using a combination of shading and hatching techniques to create a sense of depth and realism in a drawing, often used to create a dramatic effect.
