### Value

1. 1. VALUE•Value is an element of design.•defined as the lights and darks inan art work.•black, white and ranges of grays.•Value can be a color and thelights (tints) and darks (shades) ofthat color.
2. 2. LIGHT• We see light through waves of energy traveling through the air that are recognized by light and color sensitive receptors in our eyes.
3. 3. • Light moves in straight lines, a SHADOW results from something blocking the light.
4. 4. Key• The relative lightness or darkness of a picture or the colors employed in it; used in preference to value• High Key• Low Key• Full Value Range
5. 5. Drawing Assignment: Value Scale A gradation of value from light to dark.• Draw 10 equally sized boxes to create a scale.• One box will be white on one end, one box black on the other end.• Develop the gradations of value in the boxes in between using pencil or charcoal.
6. 6. Drawing Assignment: Value Reduction1. Use a sheet of paper from your drawing pad (18x24)2. Use only two values to create a high contrast study based on a still life.3. Squint your eyes to reduce color effects so that you see only patterns of light and dark.4. You are to reduce all values in the subject to either black or white. Note both the actual values of objects and the light patterns on them, and classify these values as either black or white5. Draw the subject lightly in pencil; then use your black ink or gouache (Ivory Black) to make everything that is darker than the midpoint value a flat, unmodulated black.6. Erase the pencil lines, leaving the rest of the drawing white. Values will cross over objects and negative space; value will not necessarily be confined to an object. The drawing will be spatially flat, very dramatic, and somewhat abstract.
7. 7. Drawing Assignment: Sphere-6 Categories of Light• Recreate a sphere in light using charcoal, labeling the six categories of light
8. 8. Modeling• modeling. in drawing, painting, and printmaking, the rendering of a form, usually by means of hatching or chiaroscuro, to create the illusion of a three- dimensional form
9. 9. CHIAROSCURO• In drawing and painting, the use of light and dark to create the effect of three-dimensional, modeled surfaces
10. 10. Representing the Effects of Light• Realistic• Expressive• Emphasis
11. 11. Atmospheric Perspective
12. 12. Expressive use of light
13. 13. Emphasis
14. 14. • Tenebrism--violent chiaroscuro, dark manner used to lend mood or emotional expression, typical of Rembrandt Rembrandt Drawing at a Window
15. 15. Dramatic use of light and dark
16. 16. Materials Needed• Vine and willow charcoal• Charcoal pencils, one soft, one medium• Kneaded eraser• White eraser• Higher quality paper• Spray fixative• Tape
17. 17. Additive Reductive Process• Tape paper evenly around edges to create a border• Use vine or willow sticks and apply evenly to paper, covering the entire surface• Aim for middle range value• Use vine or willow to draw preliminary sketch
18. 18. Additive Reductive Process• Use soft charcoal pencil to shade in darkest values• Medium charcoal pencil for medium values• Use kneaded eraser to create the light values• Use white eraser for highlights• Work from general to specific• Leave details until the end
19. 19. Additive Reductive Process• Spray fix to keep charcoal from smudging or falling from paper• Remove tape by pulling away from the drawing
