Why do movies always wet the street floor when shooting on location at night?

Oh, it's so easy. The use of water wetlands is the same at night and during the day. Because there must be lights in the night show, and the lights are all shining side by side on the ground, like ordinary streets are all cement and white. When the light comes down, it will reflect light, and the effect of the camera will be a very bright background, which will grab the picture. But after the water is paved, the whole floor will be dark, and the cement floor will be dark after absorbing water. When the light is on, there will be no more large-scale reflection. Of course, no crew will make a sea when the ground is wet. It is usually wet, so there will be no mirror reflection of water. This is often done when shooting during the day, and there will be watering cans prepared by the on-site staff and brothers, not just the ground, walls, stones and so on. I have been with the crew all the year round, and I know this very well. It's okay. Go up and spray.
