Day to dusk (interior)

Relight a daytime photo of a room as a dusk, evening or night shot.

Day to dusk relights a daytime photo of a room for the hour you pick: the sky in the windows turns, and from dusk on the lamps, ceiling fixtures and accent lights already in the photo come on. Furniture, finishes and the layout stay as photographed. It gives a listing, a hotel room or a short-let an evening image without a second shoot at the right hour.

This tool is built for interiors and treats every photo as a room. For a building's exterior — a facade, a garden, a pool — use day to dusk for exteriors (day-to-dusk-exterior).

Options

Every option has a default, so an empty options object gives a dusk shot (20:00) of a room with windows, keeping the real view. Send options only when you need something other than that.

Example

{
  "tool": "day-to-dusk",
  "image_url": "https://example.com/living-room-noon.jpg",
  "options": {
    "timeShift": 20,
    "hasWindows": true,
    "viewType": "none",
    "season": "none"
  }
}

Tuning the result

timeShift is the target hour on a 24-hour clock, from 0 to 23. The default of 20 is the dusk look most listings want: the room's lights are on and the sky in the windows still has colour. Lower values move toward golden hour and afternoon, with warm sunlight falling across the floor and walls; higher values move toward night, where the room's own lights carry the image.

hasWindows defaults to true. Set it to false for a room without windows — a bathroom, an inner hallway, a basement: the hour is then expressed through the room's own light alone, nothing is said about windows or sky so none are invented, and viewType and season are ignored.

viewType controls what is seen through the windows, and defaults to none, which keeps the real view and only re-lights it for the hour. Use it when the real view works against the photo — plain-white to remove a distraction, or a scene such as ocean or city-skyline where that matches the property.

season defaults to none. It dresses only a scene you render with viewType — autumn trees in a forest view, snow on a mountain range. With none or plain-white it is ignored, so the real view through the windows is never re-dressed.

With tier: "custom", customPrompt adds your own direction to the conversion — warmer lamplight, a moodier evening. It is applied through light and atmosphere only; it is not a way to move, add, remove or restyle anything in the room.
