A gobo is a stencil or template used in lighting design to create patterns or images when light is projected through it. Typically made from metal or glass, gobos are placed in front of a light source, such as a theater spotlight or LED projector, to cast shapes like leaves, clouds, or custom designs onto surfaces. They are commonly used in theater productions, concerts, and events to enhance visual storytelling. Gobos can be used for various purposes, including creating ambiance, highlighting specific areas, or adding artistic elements to a scene. They are an essential tool for lighting designers and can transform ordinary spaces into visually engaging environments.
