AI relight — upload a photo, move the light
Set where the light comes from, how high it sits and how strong it is. The shadows and highlights are redrawn to match. The subject stays as it was.
Ten runs, full resolution, no watermark.
What relighting does
Relight is a tool inside Keter Labs, an AI creative studio. You upload a photo and place a single key light, and the model recomputes the shadows, highlights and colour temperature to match where you put it. It changes how the scene is lit, not what's in it.
- Takes
- A photo you already have
- Changes
- Where the light comes from, and how strong it is
What you can set
| Control | Range |
|---|---|
| Position | Drag the light, or pick a quick position |
| Rotate | −180° to 180° around the subject |
| Elevation | 0° to 90°, from level with the subject to directly above |
| Intensity | 0 to 100 |
How to relight a photo

Generate and compare
Move the light and run it again to see the same shot lit differently.

Not a set of lighting presets
There's no library of named lighting looks to apply and no preset file to download. You place one light yourself and the model works out the rest. If you want a repeatable look across a whole shoot, a preset pack in your editor will hold more consistent than running each photo here.
What this tool doesn't do
One light per run. There's no fill or rim light.
No colour temperature control, although the model recomputes it to match the new light.
No separate control for how hard or soft the shadows are.
It can't remove a hard shadow that's already in the photo.
Reflective and transparent surfaces relight less predictably.
You get a finished image, not a layered file.
Who it's for
Product photographers
a second lighting direction without setting the shot up again
Marketing teams
an older photo matched to the lighting of a newer set
Designers
checking how a composition reads with the light on the other side
Frequently asked questions
Can I change the colour of the light?+
Not directly. You set direction, height and strength. The model recomputes colour temperature to match where the light now sits, but there's no warm or cool control.
Does it change the subject?+
No. The subject, its geometry, its materials and the composition stay as they were. Only the lighting and the shadows that follow from it change.
Can I add a second light?+
No. Each run places one key light. Running it again with the light somewhere else gives you another version to compare, not a second light in the same image.
Will it fix a badly lit photo?+
It can change where the light comes from and how strong it is. It can't remove a hard shadow that's already burned into the original.
Which light position should I start with?+
A light off to one side at around 45 degrees elevation gives the most familiar shape, because it's close to how daylight falls. Drop it lower for longer shadows, or raise it for flatter, more even light.
Does it work on people as well as products?+
Yes, and the controls are the same either way. Faces and skin tend to show a lighting change more clearly than a flat product surface does.
Is it free?+
New accounts get 30 welcome credits, which covers ten runs. Each one after that costs 3 credits. Output is full resolution with no watermark.
