A focused day-to-night workflow

Nothing moves but the light

The preset keeps composition, buildings, and subjects locked while changing the time of day.

Light sources come alive

Windows, street lamps, and signs glow naturally with soft pools and long shadows.

Compare against the source

Use the reference-image comparison to confirm the scene geometry never drifted.

How to turn a day photo into night

The preset supplies the relighting direction while the ImageStyle workspace keeps the prompt and output settings editable.

  1. 1

    Upload a daytime scene

    Buildings, streets, and landscapes with visible windows or lamps transform most convincingly.

  2. 2

    Review the night prompt

    The night-relighting direction is prefilled. Keep it, or ask for dusk tones, blue hour, or deeper night.

  3. 3

    Generate and compare

    Inspect the night version beside the original, then refine or download the result.

What to inspect in the night version

Light placement is plausible, not measured
The preset invents lamp and window light where it fits the scene. Check that it reads naturally.
Very flat skies simplify
Overcast or empty skies may become generic night gradients. Try dusk for richer skies.
Use source material you can share
Only upload photos and references that you are allowed to use for the intended project.

Day to night photo FAQ

Will buildings and people stay in place?
Yes. The preset changes the light, not the scene — composition and subjects stay locked to the original.
Do I need to write a prompt?
No. The night direction is prefilled and editable. Generate as-is or ask for dusk or deep night first.
Can I go the other way, night to day?
The preset is tuned day-to-night. For the reverse, describe the daylight target in an edited prompt and check results carefully.
What happens to my uploaded photo?
The image is uploaded to the same reference-image workflow used by the ImageStyle generator. Review the current privacy and storage terms before using sensitive material.
