Vertical 9:16 video, 10 seconds long. A quiet city sidewalk at dusk, blue hour lighting. One streetlight stands directly above the sidewalk in the center of the frame. The camera is static, eye-level. At second 3, a lone human adult walks into frame from the background and approaches the streetlight. As the person passes directly underneath, the streetlight gently increases brightness by about 10–15 percent. The change is smooth and gradual, not sudden. After the person exits the frame, the streetlight slowly returns to its original brightness. No cars, no noise, calm atmosphere. End on the same lighting level as the opening frame to allow looping.
