Final answer:
Artists create a sense of depth in their paintings by skillfully manipulating values, which consist of light and shadow, to give flat images a three-dimensional effect that draws viewers into the scene.
Step-by-step explanation:
Artists can create a sense of depth by using a variety of values. When painting landscapes, artists employ a technique that provides an illusion of depth to give a three-dimensional feeling on a two-dimensional surface. The use of value, which includes light and shadow, gives shapes the illusion of mass and helps compose a piece with a sense of reality, drawing the viewer into the scene. Through strategic use of color, value, and texture, a painting can evoke a convincing illusion of space and form, making the landscape appear vast and detailed. This use of value is essential in achieving a balanced and dynamic composition that conveys the intended mood and setting to the audience.
