The window grows while the room brightens
Change only the fixed-window sentence and keep brightness amplitude the same. Compare the corner locations, not merely the overall visual warmth.
Task template
Window daylight shift: change light, preserve room geometry
Request a gradual brightening of the daylight already entering the left window while the camera and room remain fixed. The fixture is an illustration of atmosphere, not evidence of actual property sunlight or a lighting simulation.
Includes original practice inputs and a review checklist. This prompt has not been independently tested with the generation model.
Download the input image below and upload it manually in the generator; the button carries the prompt.
01Prepare the inputs
- Use the supplied room or an authorized room photo with clear window corners, sofa feet and a visible floor-wall boundary.
- Choose a brightness change within the existing daytime setup. Keep the same window side and avoid a sunset, moving sun or night transition in this version.
- Record the sofa legs, table edges and window frame before submitting. They distinguish changed light from rearranged geometry.
- Keep curtains and people out of this practice so the lighting is the sole requested change. Inspect the diagram separately; do not upload its comparison labels.
02Prompt and procedure
Copyable prompt
Use the uploaded room as the first frame and keep the camera fixed. Daylight entering through the existing window on frame left becomes gently brighter over the shot. The floor light patch remains associated with the same window and changes softly in intensity without sweeping to a new side. Keep the window frame, walls, floor boundary, sofa, table and objects in exactly their original arrangement. Nothing moves or appears. Keep a natural daytime atmosphere without a sunrise, sunset or night transition. End in a slightly brighter steady room.
Inventory fixed geometry
Note the four window corners, sofa feet and the table’s nearest edge. Compare these during review before attributing any apparent movement to light.
Limit the requested variable
Ask for gentle brightening from the current window direction. Do not add a new lamp, opening curtains or a moving sun, because each would alter the cause of illumination.
Check the illuminated surfaces
Follow the floor patch and lit sofa surfaces. Their brightness may vary, but their changes should remain compatible with the visible left window instead of creating a second opening.
Compare the brighter ending
Review the final room layout against the source and replay for exposure flicker. Save the illumination observation separately from geometry acceptance.
03Check the result
- The camera framing stays fixed without a push-in or crop drift.
- All window corners and frame divisions remain in the same places.
- Sofa legs, table edges and small objects retain their arrangement.
- The floor-wall boundary remains continuous and stationary.
- Daylight brightens gently rather than flashing or pulsing.
- The floor patch remains compatible with the original window direction.
- The ending remains daytime without new lamps, openings or furniture.
04Troubleshoot and finish
The light patch sweeps across the entire floor
Reduce only the requested change to intensity at the current patch; remove time-of-day language before changing the source.
Brightness pulses or flashes
Reduce only the brightening range and retain a gradual steady transition. Recheck the whole clip for flicker rather than judging one brighter still.
End on a calm brighter room and archive geometry and light checks separately. Any real-property claim about sunlight still needs actual dated records or footage.
