Right/left brain distinction not so simple as originally described. But really, location of processes not important for us (not operating on brain, just trying to use it better).

This book and the exercises within it very influential, although many of them in use before Edwards documented them in this text. (e.g., drawing upside down)

IMAGE BASED PROCESSING

Edges: exercises about lines, including edges and internal contour lines

Spaces: chiefly about negative space, a sort of figure and ground exercise that looks at “the other side of the line”

SURFACE-BASED

Relationships: relative positions and scale, angles of surfaces. The goal of these exercises is in large part to help you draw surfaces as you see them, not as you know they are. E.g., drawing a tilted circle as a ellipse…

OBJECT-BASED

Light & shadow: knowledge of objects and the interrelationships is necessary to do proper shading…
