Instructional book that teaches drawing by shifting perception from the logical left brain to the visual, spatial right brain, using exercises to help people see the world like an artist. Published in 1979, it has sold millions of copies and is used in art schools worldwide, with updated editions incorporating new brain research and applications for problem-solving and self-expression. The core idea is to use right-brain skills like seeing edges, negative spaces, and relationships to improve drawing ability, even for those who believe they can’t draw.
