Perspective and composition
Art & Design · Key Stage 3 · The School
One-point perspective
Draw a horizon line at eye level and mark one VANISHING POINT on it. Every edge running away from you meets there; every horizontal stays horizontal, every vertical stays vertical. A corridor, a road or a room seen straight on works exactly this way.
Two-point perspective
Turn the object so you see a corner rather than a face, and you need two vanishing points, both on the same horizon line. Verticals stay vertical; everything else runs to one point or the other. The commonest error is putting the two points too close together, which makes buildings look violently distorted — spread them wide, often off the page.
Composition
The eye enters a picture, travels, and rests. You control that with placing, contrast and lines that lead. Dead-centre is usually the weakest choice because it stops the eye immediately; the rule of thirds is a useful starting habit, not a law. Ask where you want the eye to end up, then build the route.
