# Perspective and the Illusion of Depth

A flat surface can be made to look deep using rules that were worked out and then taught: lines that converge, things that shrink with distance, colours that fade. Not every tradition wanted that illusion.

## Ready when they can

- Find the horizon line and a vanishing point in a picture that uses them
- Name two tricks besides converging lines that make depth, such as overlap or paler distant colour
- Compare a picture built on perspective with one that stacks figures flat, and say what each is for
- Explain that linear perspective was invented at a time and place, not always used

## Lesson: Making a flat page look deep

Stand on a straight road and look far ahead. The edges seem to meet at one far point. Artists copy that trick to make a flat page look deep.

Draw a line where the sky meets the land. That is the horizon line, and it sits at your eye level. The spot on it where parallel lines meet is the vanishing point.

**Example.** Look at a photo of railway tracks. The two rails run side by side, yet in the picture they meet at one point on the horizon. The far train looks tiny, and the far hills look pale and blue.

**Tip.** Not every picture wants depth. A picture that stacks figures flat keeps each one clear, which suits telling a story in order. Linear perspective was worked out in Renaissance Europe and taught on, so a flat picture is a choice, not a mistake.

**Recap.** Converging lines, smaller far things, and paler far colours build depth, while flat stacking serves a different purpose.
