1 Flesch-Kincaid Grade Level: 6.8 Flesch-Kincaid Reading Ease: 67.6 Drawspace Curriculum..A - 6 Pages and 0 Illustrations Use Shading to Create Forms Use value maps and graduated shading to turn a circle, cube, and rectangle into realistic three-dimensional forms Resource:..R How to Use a Value Map Activitiy:..A Shade Graduations of Values Supplies: paper, H, HB, B, B, and 6B pencils; pencil sharpener, sandpaper block, kneaded and vinyl erasers This tutorial has four sections: Outline a Circle, Cube, and Rectangle Identify Values in the Reference Image Outline the Shapes of Values Add Shading to Your Drawing As an Aside The white paper used for the drawing in this activity has a rough tooth. Also, very little pressure was applied to the pencils during the process of adding shading. Therefore, the graphite sits mostly on the paper s peaks, and the tiny crevasses in the paper are visible as gorgeous little white specks. Outline a Circle, Cube, and Rectangle. Use a H pencil to lightly sketch a circle, cube, and rectangle. Your goal is to simply place each subject on your paper proportional to the corresponding drawings in Figure. Your drawing of these three subjects should be no smaller than 8 in (0. cm) wide. Realistic shading is more diffi cult to render in a small drawing than in a large one.. Lighten your sketch lines with a kneaded eraser and neatly outline each subject more accurately with a sharpened HB pencil (Figure ). ISBN: Copyright 0 Drawspace Publishing and Brenda Hoddinott.

2 Drawspace Curriculum..A Do not apply too much pressure to your pencil; you may want to lighten these outlines later. Figure Identify Values in the Reference Image. Create a value scale of the base value of a H, HB, B, B, and 6B pencil (Figure ). Number the values from to. This value scale can help you locate each base value in your reference image, and can serve as a guide when you add shading to your drawing.. Identify the locations of each value in the reference image. Refer to the completed drawings in Figures and 0. When you know where the different values are located, you can more easily identify their shapes. The frontal face of the cube and the cylinder are made up of graduations that are long vertical rectangles. Compare their values to those in your value scale. Figure The shapes of the values on the side of the cube are less distinct. They graduate from light (or white) at the top edge to medium at the bottom edge. Locate each of these values in your value scale. The shapes of the values in the sphere are more diffi cult to identify because they follow its perceived contours. Refer to Figure to get an idea of what you need to see. These numbered values should correspond to the numbered values of your value scale.

3 Drawspace Curriculum..A Figure You can darken or lighten the values in your value scale if they are not close to the corresponding values in Figures and. Outline the Shapes of Values. Peek ahead to Figure 0, and Identify the size and shape of each different value. 6. Use a H pencil to lightly outline each shape on your contour drawing. Figure This illustration has been darkened in Photoshop so you can see the outlines clearly. To help keep you on track, you can use a H pencil to very lightly mark the numeric name of each value inside each of its outlined shapes. Add Shading to Your Drawing 7. Sharpen your H, HB, B, B, and 6B pencils to a chisel point. 8. Use a kneaded eraser to pat your drawing until the value map is very faint. ISBN: Copyright 0 Drawspace Publishing and Brenda Hoddinott.

4 Drawspace Curriculum..A Tip! The completed drawings of the sphere and cylinder have a section that is left white (highlights). You have the option of adding shading to the side of the cube with or without a white section. You can begin the lightest value: a little ways down from the upper edge (Figure ). at the upper edge (peek ahead to Figure 0). 9. Use each pencil in turn to add shading to your contour drawings (Figures to 0). Place your value scale beside you as you add shading to your drawings. Remember to graduate the values in between each shape. Figure Graduation : (H pencil) the lightest graduation of all with values that range from almost white to light. Figure 6 Graduation : (HB pencil) a light graduation with values that range from light to medium. ISBN: Copyright 0 Drawspace Publishing and Brenda Hoddinott. All rights reserved.

5 Drawspace Curriculum..A Figure 7 Graduation : (B pencil) a medium graduation with a full range of medium values that range from the lighter medium values to the darker medium values. Figure 8 Graduation pencil) a the lightest Graduation : : (H (B pencil) dark graduation with graduation of all with values that range values that range from the darker medium values to from almost white to light. the lighter dark values.

6 6 Drawspace Curriculum..A Figure 9 Tip! To create a value map for any subject, identify its individual values and then outline their shapes on your contour drawing. To create an even smoother overall graduation, you can add an additional thin rim of Value between Values and in the section of reflected light in the lower left of the sphere. Figure 0 Graduation : (6B pencil) the darkest graduation with values that range from the lighter dark values to the darkest values of all. 0. Compare your drawing to Figure 0 and touch up any sections of shading that don t graduate smoothly. Gently pat a section of shading that is too dark with a kneaded eraser. Use a little more pencil pressure or a darker grade of pencil to darken shading that is too light. ISBN: Copyright 0 Drawspace Publishing and Brenda Hoddinott. All rights reserved.
