Focused AI image workflow
Image Relight
Change the perceived lighting of an image by describing direction, color, softness, and mood while keeping the scene subject in place.
How to use it
1
Upload the lit scene
Use a source where the subject, materials, and existing shadows are visible enough to guide the edit.
2
Describe the new light
Specify source direction, hardness, color, time of day, and which parts of the scene should remain recognizable.
3
Review material response
Check faces, skin, reflective surfaces, cast shadows, and background consistency in the generated variation.
Useful for
- Explore a different campaign mood
- Test day-to-night or warm-to-cool directions
- Create lighting references before a photo shoot
Expected result
GPT Image 2 creates a relit image concept based on the source and written lighting direction.
Limitations to review
The page does not expose physical light controls or masks. Reflective materials, faces, and shadows can change beyond the requested lighting edit.
Frequently asked questions
Can I add a light from a specific side?
Yes. Describe the side, height, softness, and color of the source, then check whether the shadows and highlights follow that direction.
Will the subject remain unchanged?
The prompt asks for subject preservation, but generated lighting can alter faces, texture, and edges. Review the source and result together.
