A person holds a black camera labeled 'M645 SUPER' with their left hand, while their right hand approaches the top of the camera. The right hand lifts a small black cover and begins to insert it into the top of the camera. The cover is gradually pushed further into the camera, aligning it properly. The cover is almost fully inserted, with only a small part still visible. The cover is now completely inside the camera, and the person's hand is still holding it.
