What is a bump in theatrical lighting?

A bump in theatrical lighting refers specifically to a quick flash of light that typically signals a cue or a specific moment in a performance. This technique can serve various purposes, such as marking a scene change, highlighting a particular action, or emphasizing dramatic moments. The sudden nature of a bump creates an immediate visual effect that captures the audience's attention, helping to enhance the overall theatrical experience.

In the context of stagecraft, it is crucial for lighting designers and technicians to understand how and when to utilize bumps effectively to support the narrative and emotional tone of the performance. While other choices may relate to theater in different ways, they do not accurately describe the function and definition of a bump in lighting.
