This document introduces different types of drawing techniques, including blind contour drawing where the artist only looks at the subject and not the paper, modified contour drawing where the artist looks mostly at the subject and briefly at the paper, and cross-contour lines that show the three-dimensional form of a subject across its shapes. It also discusses gesture drawings that capture movement through quick sketches, and using value, or light and dark shades, to convey form in two-dimensional drawings. Famous artists like da Vinci, Rembrandt, Picasso, and Escher employed various techniques.
