Images of Madeira Beach, Florida, from video taken June 20, 2017. Left: Snapshot (first frame of video). Right: Time-averaged image, created by averaging the intensity of light recorded at each spot, or “pixel,” during the video. The pale band offshore reveals where a sandbar caused waves to break. On the beach, the line between wet and dry sand shows the maximum wave runup during the video.
