Uplighting, Downlighting & Grazing: A Guide to Lighting Techniques

Outdoor lighting design isn't about buying better fixtures — it's about knowing where to put them and why. Here are the core techniques, and what each one is actually for.

Uplighting

A fixture at ground level aimed up at a tree, wall, or architectural feature. It's the most-used technique in landscape lighting because it creates drama and height that nothing at ground level can. The key is cross-lighting: two or three fixtures aimed from different angles produce a three-dimensional form, where a single head-on fixture flattens the subject into a silhouette.

Downlighting and Moonlighting

Fixtures mounted high — in a tree, a pergola beam, or under an eave — aimed down. Light filters through branches and structure and lands as soft, dappled shadow. It's the most natural-looking effect available, it produces almost no glare, and under one of Portland's big firs or maples it's genuinely striking.

Grazing

Placing a fixture close to a textured surface so light rakes across it at a shallow angle. Every joint and stone face casts a small shadow, and the texture leaps out. Perfect for stone, brick, and rough bark — and wrong for smooth stucco or flat siding, where it just highlights every imperfection.

Washing

The opposite of grazing: a wider beam from farther back that lays even light across a surface. Right for smooth walls, fences, and hedges where you want a soft field of light rather than texture.

Silhouetting

Lighting the surface behind an object so the object reads as a dark shape against a bright field. Superb for plants with strong outlines — Japanese maples, ornamental grasses, sculptural shrubs. It's the most underused technique in residential lighting.

Shadowing

The inverse: light the object from the front so its shadow is thrown large onto the wall behind it. A branching shrub in front of a pale wall produces a shadow far more dramatic than the plant itself.

The Principle Behind All of It

Contrast is what makes lighting work. Lighting everything evenly is the same as lighting nothing — the eye needs dark to perceive light. Restraint is the technique that matters most, and it's the one that separates a designed system from a yard with fixtures in it.
