Shading is the technique of unreliable the tonal values on the document to represent the shade of the material as sound as the placement of the shade.

Texture in the picture

Careful thought to reflected light, dimness, and highlights can result in a very practical rendition of the illustration.

Blending uses an apply to move the drawing material on the paper so as to hide the original drawing strokes. This can only be done when drawing with a material such as graphite or charcoal that is not permanently attached once applied. When shading and blending is needed, the artist can employ a combination of a tortillon blending stump, chamois or soft tissue, and a particular putty-rubber eraser. The chamois cloth in particular is useful for creating smooth textures, and for remove objects to lighten the tone.

There are a numeral of methods for produce texture in the picture. In addition to choosing a suitable paper, the type of drawing textile and the drawing technique will result in different textures.

Quality can be made to appear more reasonable when it is draw next to a contrasting texture. Thus a common texture placed next to a smoothly blended area will appear more notable. A similar effect can be achieved by drawing different tones in close proximity. A light border next to a dark background will place out to the eye, and almost appear to float above the surface.

In most sketch mediums, but especially in ink, realistic renditions of an object or structure avoid outlinining the form and features. Otherwise the image may resemble a paint-by-numbers figure from a coloring book. Instead the form of the structure is portrayed almost entirely through tones and shading, as well as contrast with the setting.
