The video begins with a close-up shot of a smartphone screen. The screen is initially black, but then a camera test image appears. The image shows a close-up of water splashing, with the water droplets clearly visible against a dark background. The person holding the phone then uses their finger to swipe across the screen, causing the image to move slightly. The camera test image is then zoomed in and out, showing the details of the water droplets and the splash. The video ends with the person holding the phone, still displaying the camera test image.
