Value: The relative degree of lightness or darkness, a.k.a. "shading"
Directions:
1. Using a range of graphite drawing pencils, complete the values scale (Download the image, or see the instructor for a copy.) by matching the values in each cell. Try using the side of your pencil.
2. Using a range of graphite drawing pencils, complete the modeled-values diagram below by making the circle look like a three-dimensional sphere, just like the example at the bottom. Try to make the values gradually change from one tonal value to another so that it looks like the lights and shadows wrap around the sphere.
