Friday morning began with a series of the Ideal Solids. Edison's drawing above combines contour lines and tone. The line work is very complementary to the tonalities. There is a gentle balance between breaking the line to accentuate highlights while darkening areas to complement the highlights and light areas. Furthermore, observe how his use additive and reductive mark-making follows the cross-contours of the forms.
In the afternoon, students made proportional studies of single objects and later groupings. Siobhan has clearly illustrated the locations of ellipses and the various ideal solids. Also note how she has used a bolder, darker line quality to advance the forms in the foreground.
