Change time of day or weather realistically

Transform the supplied scene from [CURRENT CONDITIONS] to [TARGET TIME OF DAY AND WEATHER].

Preserve the exact location, buildings, terrain, vegetation, people, vehicles, signs, camera position, composition and perspective. Change only the sky, ambient light, colour temperature, visibility, surface response and physically necessary shadows or reflections. For wet conditions add restrained, geometry-consistent dampness and reflections; for night illuminate only from plausible visible or environmental sources.

Keep local climate and season believable. Do not add dramatic lightning, impossible stars, excessive fog, new structures, extra traffic, fantasy colours or altered signage unless requested. The result should look like a genuine photograph taken from the same position under the new conditions.
