Principles of Composition and Perspective
What the exam tests
This domain tests whether you can arrange elements into a readable image and construct believable depth. Expect questions on balance, rhythm, emphasis, unity, horizon line, vanishing points, one-point and two-point perspective, and atmospheric perspective.
Core rules
- Fix the horizon and eye level before drawing objects.
- In one-point perspective, receding parallel lines meet at one vanishing point on the horizon.
- In two-point perspective, two sets of receding edges meet at two vanishing points on the same horizon.
- Depth comes from overlap, size change, placement, detail reduction and atmospheric blur.
- Balance visual weight; avoid tangents where edges touch awkwardly.
- Create a focal point through contrast, isolation or directional lines.
Worked example
For a one-point street, place the horizon at the viewer's eye level and the vanishing point on the road axis. Building tops, road edges and window lines converge toward it; figures and trees shrink as they recede. Reasoning: all receding parallel edges must share the same vanishing point, while vertical edges stay vertical in one-point perspective.
Traps
Multiple horizons, converging lines that miss the vanishing point, objects floating above the ground plane, a static centred arrangement, overcrowded corners, and ignoring eye level. A common error is drawing distant objects with foreground detail instead of simplifying them.
