You'll learn why certain configurations trigger perceptual contradictions and how to control those elements in your own drawings. The techniques transfer directly to conventional drawing, understanding how to manipulate perceived depth in trick art sharpens your ability to render convincing dimension in any subject.\u003c\/p\u003e\n\u003cp\u003eHarris works in graphite and colored pencil throughout, keeping materials accessible while demonstrating how value and color intensify illusion effects.
