Pencil shading is a drawing technique that uses varying degrees of pressure and pencil hardness to create different tones and textures. Artists apply light or heavy pressure to the pencil to produce a range of shades, from light grays to deep blacks. This technique helps to add depth and dimension to drawings, making them appear more realistic. To achieve effective pencil shading, artists often use tools like blending stumps or their fingers to smooth out the pencil marks. Different types of pencils, such as graphite or charcoal, can also be used to achieve specific effects. Mastering pencil shading is essential for creating lifelike representations in art.
