Value: Drawing and the art element of value
The document discusses value and light in drawing. It defines value as the lights and darks in a work of art. Light is described as waves of energy that our eyes perceive as light or color. Shadows result when light is blocked. Key terms like high key, low key, and full value range are introduced. Drawing assignments are outlined that involve creating a value scale, reducing values to black and white, depicting the six categories of light on a sphere, and using additive and reductive techniques with charcoal to represent form, light, and shadow. Modeling, chiaroscuro, atmospheric perspective, and tenebrism are also defined in relation to using value and light in artwork.

- 2. LIGHT • We seelight through waves of energy traveling through the air that are recognized by light and color sensitive receptors in our eyes.

- 4. Key • The relativelightness or darkness of a picture or the colors employed in it; used in preference to value • High Key • Low Key • Full Value Range
- 5. Drawing Assignment: ValueScale • 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. A gradation of value from light to dark.
- 6. Drawing Assignment: ValueReduction 1. 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 white 5. 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.

- 14. Modeling • modeling. indrawing, painting, and printmaking, the rendering of a form, usually by means of hatching or chiaroscuro, to create the illusion of a three- dimensional form

- 33. 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
- 34. 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
- 35. Additive Reductive Process •Spray fix to keep charcoal from smudging or falling from paper • Remove tape by pulling away from the drawing
