The image is a close-up of a subway tunnel at night. The tunnel appears to be underground, as there are wooden planks on the right side of the image. The walls of the tunnel are made of concrete and there are several fluorescent lights hanging from the ceiling. The lights are bright and appear to be turned on, creating a warm glow. The background is dark, making the lights stand out even more. The image is taken from a low angle, looking up at the lights.
