POINT AND FLAT SHADING
The first step to successful pencil shading is to control the movement of your pencil by making sure that every mark you make on the paper works towards creating the shading or exhibiting effect that you want. Side shading has a grainier, softer look and covers a large area quickly Using a sharp point to shade allows one to control more and you can do much finer work and get a greater range of tone out of the pencil.
Use a light touch with the pencil and work an area in an irregular, overlapping pattern to gradually build up the graphite on the page.
Use line weight in shading
When using directional shading one can change the pressure on the pencil to create light and dark tones. Monitoring it very precisely can allow one to model smooth forms. A more relaxed approach to lifting and re-weighting the pencil for a fairly nonstop line is useful for creating highlights across textures like hair or grass.
Change the pencil direction at irregular intervals, making one stroke long and then next short, overlapping where needed this will prevent unwanted banding through shaded area.
Pencil shading problem
When pencil shading, the first thing most people do is to move the pencil back and forth in a regular pattern, with the ‘turn’ at the end of each movement roughly parallel. The trouble is that when you use this technique to shade a large area that even edge gives you a dark line through your area of tone. Sometimes it is only delicate but often it looks very clear and disturbs the illusion that you are trying to create with your pencil shading.
