The document discusses different elements of art, including closed form (represented by an origami picture showing the full form), open form (a picture with lines extending beyond the page), scale (a photo by Ansel Adams showing trees of different sizes and distances), linear perspective (a road receding into the distance), atmospheric perspective (a picture with cooler colors in the background), lighting (how highlighted and shadowed areas appear closer and farther), and texture (raindrops creating texture on glass).
