Overlapping and Staggering Elements
Overlapping objects, one in front of the other, can make them appear as if they are on different planes within a scene, providing a sense of depth and dimension. Placing a background element behind a foreground element pushes the background element into the distance, making it appear even farther away. And you can increase the illusion of depth by staggering the elements of your composition: Instead of placing elements side by side (on a horizontal plane), try placing them at different levels and heights within the scene.
SIZING AND OVERLAPPING OBJECTSThe house pictured here would be taller than the fence if the two elements were placed side by side—but enlarging the posts makes the fence appear to be closer. Similarly, overlapping the house with the tree pushes the house farther into the distance, creating a more realistic sense of depth.
