Review Questions

• How does the use of a gobo enhance the overall visual impact of a theatrical production?
  • Using a gobo enhances a production's visual impact by projecting images or patterns that complement the story being told on stage. This added layer can create specific moods or themes, guiding the audience's emotional response. By integrating visuals with lighting design, gobos help establish the setting and atmosphere more effectively than lighting alone.
• Discuss the differences between metal and glass gobos and how each impacts lighting design in performances.
  • Metal gobos typically produce sharper images and are often used for bold shapes or patterns that require high contrast.
