Art Lesson: Creating Depth. Create the illusion of three-dimensional imagery. Mastering the ability to create depth in art takes practice and patience. Draw distant objects small than close objects. Incorporate the effects of atmosphere that decrease visibility of objects farther from the viewer. Reduce detail as the background diminishes with mountains and other objects appearing only as silhouettes. Other techniques to imply depth may include reducing color in the background to reinforce the concept of distance between images. Warm colors appear closer to the viewer, while cool colors appear farther. It should be noted that a full range of colors might be unneeded. Using three or even only two colors can make a coherent image with an exceptional sense of depth.
