What does the term "fade to blackout" imply in theatre production?

The term "fade to blackout" in theatre production specifically refers to a gradual decrease in stage lighting until the stage is completely dark. This technique is used to create a smooth transition between scenes, to signify the end of a segment, or to enhance dramatic emphasis. It allows for a gradual dimming of lights, which maintains the audience's focus and can create suspense or a moment of reflection before moving on to the next scene. This is especially effective in giving the audience time to absorb the closing moments of a performance or scene before the lights go out completely.

The other options do not accurately describe this specific lighting technique. Ending a performance doesn't necessarily involve a gradual dimming but rather might indicate a final blackout. The transition from rehearsal to live performance is a broader concept that involves many elements beyond just lighting, while switching on all lights at once is the opposite of what "fade to blackout" suggests, as it implies an abrupt change rather than a gradual one.
