A camera operator is like a person who uses a special box that takes pictures and videos. Sometimes, they move it around to different places to get the best view of what they want to capture. They also make sure that the pictures and videos look good and clear, so they might adjust some buttons and knobs on the box. Think of it like playing a game with a screen, but instead of buttons, the camera operator holds a big box with buttons and lenses to capture the best moments.
