A seasoned instructor of linear perspective, Connors shares a brief overview of the significance and history of perspective in art, then leads you through a series of drawing exercises designed to strengthen your perceptual skills and explore compositional strategies. You’ll see how these strategies have been employed by other artists and learn how to make your own compositional tools. Using a model landscape, you’ll refine your ability to visualize a scene then explore atmospheric perspective by building up a sketch with tonal masses.
