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