Change the apparent light direction, intensity and color of a photograph to explore a different visual emphasis. The interactive preview is useful for portraits, products and creative lighting studies.
The workflow estimates scene information and uses a shader-based rendering step to simulate how a movable light affects the image. Controls change the light position and energy rather than simply increasing global brightness.
Relighting from a single flat image is an approximation. Hidden geometry and true material properties are unknown, so strong settings can produce unnatural shading.
The tool cannot reveal real detail that is clipped to pure black or white. Results depend on the estimated scene representation, and reflective or transparent surfaces may not respond physically accurately.
The relighting pipeline uses browser-side model and rendering resources. Initial model loading requires a network connection, while interactive adjustments are designed to occur on the device.
No. It simulates a positioned light with direction and falloff rather than applying one global brightness value.
It may improve the appearance, but detail clipped from the source cannot be recovered reliably.
The interface provides a movable light position, one intensity slider and a light color picker.
A single image does not provide complete geometry or material information, so the rendering is approximate.
AI Creator tools run in modern desktop browsers.
RELIGHTING FIELD NOTES
Relighting a single photograph is an approximation because the system cannot observe hidden geometry or the complete material response of the scene. The most believable result respects the direction already suggested by the face, objects and background instead of treating light as a flat brightness filter.
Before moving any control, identify the brightest side of the subject, the direction of cast shadows and the color of ambient light. Place the new light in a direction that the visible geometry can support. Large directional changes are harder to believe because an edited highlight may move while the original shadow stays fixed. Start with low intensity and increase strength only after the overall direction feels coherent.
Skin, metal, glass, fabric and matte walls respond differently. Watch for uniformly bright surfaces, clipped facial highlights, glowing hair edges and reflections that no longer point toward a plausible source. Compare the subject with the background: a strongly relit face inside an unchanged dark room can look pasted in. Neutralize the color temporarily to judge contrast before deciding whether a colored light improves the scene.
A subtle lighting discontinuity may be acceptable in a small social graphic and obvious in a large portrait. Switch between the original and result at the same size, then step away from local details and check the visual hierarchy. The edit should guide attention without changing identity or hiding important product features. Keep the source because repeated relighting passes can compound contrast and color artifacts.
