# Perspective and the illusion of depth

Artists can suggest depth using converging lines, relative size, overlap and changes in colour. These clues depend on the scene and viewpoint. Flatter arrangements can serve other artistic aims.

## Ready when they can

- Explain what the eye-level horizon and a vanishing point mean in the level-ground perspective model
- Name two tricks besides converging lines that make depth, such as overlap or paler distant colour
- Compare described deep-space and flat-row arrangements with their stated artistic aims
- Explain that the geometric linear perspective studied here developed in Renaissance Europe and was not used by every artist

## Lesson: Making a flat page look deep

Foreground and background describe pictured space. Perspective can suggest depth on a flat page. In the level-ground perspective model, the horizon marks eye level. Hills or buildings can hide it; a hill's outline need not be the horizon.

Parallel edges stay equally far apart in real space. Horizontal means level; receding means going away from you. Parallel horizontal edges receding in one direction appear to approach one vanishing point on the horizon. Drawn level railway rails seem to converge; the real rails stay apart.

Overlap means one opaque shape hides part of another, suggesting it is nearer. A tower covering part of another tower can give this depth clue.

From a fixed viewpoint, equal-sized objects look smaller farther away. In haze, distant hills may look paler or bluer. These clues do not apply to every object or scene.

The geometric linear perspective studied here developed in Renaissance Europe. Earlier artists also suggested depth. Artists have not always used this system.

Depth can suit an illusion of a room. Flat rows can help organise a story or pattern. Compare an arrangement with its stated aim.

**Recap.** Horizon, convergence, relative size, overlap and haze can suggest depth. Flat arrangements can serve other aims.
