The phrase “Lights, camera” is often used as part of the expression “Lights, camera, action!” in the world of filmmaking. It’s a traditional call used on movie sets to signal the start of filming. Here’s a breakdown of the phrase:

• “Lights”:  This refers to the lighting setup on the set. Before filming begins, the lighting crew ensures that the lighting is properly configured to achieve the desired look and atmosphere for the scene.
• “Camera”:  This refers to the camera crew and equipment. The camera operator and other crew members ensure that the camera is set up correctly, and everything is ready to start recording.
• “Action”:  This is the signal for the actors to begin their performance. Once “action” is called, the scene is officially in progress, and the cameras start rolling to capture the performance.
