As soon as you finish a line drawing of your subject that you are ready to begin the process of shading. The purpose of shading is given to the subject three-dimensionality. When you are done with shading, the subject must appear to be anchored in space and not just an object in a plane.
Values (or tones) are, by definition, degrees of darkness and lightness. It is good practice to develop a visual sense of at least five values or tones. To help with this, I suggest making a five-value scale. Draw five boxes next to each other and make the first left entirely in black, leaving the far right completely white. Then fill the center with a value that is only between black and white. This value was called the "halftone" or "medium gray." Then complete the second box from the left with a value is between black and medium gray. This value is called "dark gray". Finally, fill the second box on the right with a value that is right in the middle between white and gray. This value is called "gray."
These five values are enough to start and you can do wonders for your pencil portrait. Practice these five values until you can instantly recognize when you see them. Now, armed with the knowledge of these five values can now approach our line drawing and has drawn several shapes with different values. Now we can start the shading process (ie, the application of values.)
One thing you must always have into account as the shade is the location of the light source or light sources. At first it is better to work with a single source of light. Every value you observe should be seen as a function of where the light source is located. Each value is applied should make sense in relation to the source of light. Assign to each of the areas in your line drawing one of the five values they have internalized. You do that through careful observation. Later, the boundaries between areas producing different values are mixed call a transition zone that has a value between the two values of the adjacent areas.
To help you further, it is good to think in different areas of high value in terms of the five elements of shading:
1. Halftoning
This is the value in the middle of its scale of values. You may think this value represents the true value of the subject without the effects of direct light or shadow. It is neither light nor dark.
2. Full of light
This is the value of the areas where the light hits the subject head on. It is the white paper. This value type is also called a climax.
3. Cast Shadow
This is the darkest value to the black in the first box on the left of your value. This value occurs in places that are completely protected from any light source or reflection. These areas are usually found in the shadows the subject of models in other areas.
4. The shadow edge
This is the dark gray located in the second box on the left in its scale of values. This type of value is in areas that are not entirely in the shadows, but are beyond half measures. These areas are often between a halftone zone and a zone of light reflected or between a halftone zone and a shady area.
5. Reflects light
This is a value that corresponds to light gray, the second box on the right in its scale of values. Reflected light often can be found as a small group between a shadow and a shadow edge. It is the light that bounces off your subject from surrounding surfaces. The bottom of the jaw often shows reflected light. Never make this kind of value totally white because it never is. These areas reflect light are important warning and do as they contribute significantly to the appearance of roundness and three-dimensionality of the subject.
In conclusion, a successful online meeting with his knowledge a five-value scale and the five elements of shading that will give you a good start in developing your shading skills. Work with short strokes and mixed areas adjacent to a value that lies between the two areas. A ball on a table illuminated by a light source is a good setting for the practice of the five elements of shading.
