Chiaroscuro: (noun) the use of directional light to achieve volume and high contrast
The value scale (shown below) shows changes from absolute black (100%) to absolute white (0%).
Note: there can be an infinite number of grays between the two.

1-4a: Sketchbook Exercise— 3 Value Scales
1-4a: Sketchbook Exercise— 3 Value Scales
The value scale shows a range from white to black with gray values in between. The number of boxes in the scale can vary, but the grays should become lighter or darker in regular intervals. Another word for value scale is grayscale.
In your sketchbook, using your drawing pencils, and a ruler, draw THREE 5-inch x 1-inch rectangles in your sketchbook.
Divide the first rectangle into 1-inch boxes like the five-step value scale. Shade the boxes to match the five-step value scale. In the boxes, you should see black, dark gray, medium gray, light gray, to white.
Now, make a ten-step value scale. Divide the rectangle into ½ half inch wide rectangles. There will be ten of the shapes. Shade the boxes to match the ten-step value scale. Notice in the scale below, there is a progression from black to white, with evenly distributed gray values in between white and black.
In box 3, create a blended value scale box. (no division line necessary) Notice the scale is blended evenly. (use your blending stump to help if you prefer).

Tutorial Video: Value in Graphite
You will need a scrap piece of paper and you HB pencil. On the scrap piece of paper, try to mimic the movements shown in the video. These short, repetitive marks are called hatch marks. Start with light pressure and slowly increase pressure over time to build areas of light and dark value.

1-4c: Sketchbook Exercise— Creating Form with Value (~30 min)
Please read through the entire list of instructions before beginning the exercise.
You will need your sketchbook, HB, ~B4, and ~B8 pencils
Find some sort of organic form that’s about the size of your fist (like a rock, piece of bark, smushed and formed playdough or clay, magnolia seed pod, etc.—in a pinch you could wad up and shape a couple pieces of bread.) Reference the shape in the drawing above when you’re looking for an object to draw. The key is for the object to have form (form means a 3-dimensional shape with volume) that is organic (organic means irregular, asymmetrical, not geometric.) .
Place your organic form in directional light so that it has shadow on its surface.
Use hatch-marks to draw your organic form.
Avoid using contour line.
Build the drawing out of all over blocks of hatching/shading that describes the tone and direction of the surfaces of the object.
It is important to recognize the ‘feel’ of the direction of the shapes in the object’s surface as you add the hatch marks. If the plane is moving back in space, make the marks move back in space. If the surface is rounding, make the marks curved. If the surface is on a diagonal plane, make the marks diagonal.
Spend around 20 minutes drawing, starting with the HB pencil and building in value to the B4 and the B8.
Finish your drawing by adding a few important contour lines. Notice how the contour line width changes in the example drawing above. This change in line width reflects a change of pressure and speed as the artist draws the line.
Save this drawing to photograph/document later!
