Movie Terms Wiki Filmmaking

Gobo

A device placed in front of a light source to control the shape and direction of the light beam.


Definition

The term “gobo” comes from “go-between” — it’s an object that blocks or shapes light. In film lighting, gobos are often used to create patterned shadows or to prevent light spill.

Types

  • Patterned Metal Gobos — Cut with designs like window frames or foliage.
  • Custom Cutouts — Made for specific set designs.
  • DIY Gobos — Cardboard or foamcore shapes for quick adjustments.

Uses in Cinematography

  • Creating naturalistic effects like sunlight filtering through blinds.
  • Adding texture or depth to otherwise flat lighting setups.
  • Controlling light in confined spaces.

Practical Example

In noir-inspired films, gobos are essential for producing the iconic Venetian blind shadow effect.

Technical Note

Goboes are also common in theater and photography but in film they are often used alongside flags, scrims, and silks for comprehensive light control.
