Relight is the Nodespell Creative Tool for changing the lighting of an existing image while keeping it recognizable. You either design up to three lights (key, fill, and rim) on an interactive 3D stage with exposure, softness, and color, or you give Relight a second image whose lighting it should match. Each run returns a new image take.
When should I use Relight?
Section titled “When should I use Relight?”Use Relight when the content of an image is right and only the light needs to change.
| If you want to | Use |
|---|---|
| Place and shape lights yourself | Relight, Design lighting |
| Copy the lighting of another image | Relight, Match reference |
| Change content, not just light | Image Editor |
| Set a lighting style while generating a new image | Cinematic Shot |
| Adjust exposure and color without AI | A color node; see Color correction |
Design new lighting
Section titled “Design new lighting”- Open Create, select All tools, and choose Relight.
- Add the image under Source image with Choose assets.
- Leave Relight method on Design lighting.
- Choose a Lighting preset, such as Golden hour or Product softbox. The preset sets up one to three lights.
- On the Lighting stage, select Key, Fill, or Rim to pick a light, then drag it to a new position and adjust Exposure, Softness, and Light color.
- Open Lighting notes to add mood, contrast, shadow, or preservation notes if needed.
- Set Generations from 1 to 4, then select Generate.
Match the lighting of a reference image
Section titled “Match the lighting of a reference image”- Add the Source image.
- Set Relight method to Match reference.
- Under Lighting reference, choose the image whose lighting should guide the result.
- Choose Reference influence: Subtle, Balanced, or Strong.
- Select Generate.
Match reference works only with models that accept two images. If the current model cannot, the method shows “Choose a reference-capable model to match a lighting reference.”

Editing any light, or adding or removing one, switches Lighting preset to Custom. Double-click the Exposure, Softness, or Color temperature slider to reset it.
Use the lighting stage
Section titled “Use the lighting stage”The Lighting stage is an interactive 3D view of your lights around the subject.
| Action | Result |
|---|---|
| Drag the control sphere | Rotates the selected light freely |
| Drag the X, Y, or Z ring | Rotates around that world axis |
| Drag the outer yellow ring | Rotates around the view axis |
| Click a light | Selects it |
| Arrow keys | Rotate around X and Y |
Q and E |
Rotate around Z |
| Reset camera view | Returns the stage view to its start |
All stage gestures use the primary button, so they work on a trackpad. If the browser cannot show 3D, the stage reads “The 3D lighting preview is unavailable in this browser.”
Which models work with Relight?
Section titled “Which models work with Relight?”Relight uses a fixed list of image models and has no Featured section.
| Model | Design lighting | Match reference |
|---|---|---|
| Nano Banana 2 (default) | Yes | Yes |
| Nano Banana 2 Lite | Yes | Yes |
| Nano Banana Pro | Yes | Yes |
| Seedream 5 Pro | Yes | Yes |
| GPT Image 2 Edit | Yes | Yes |
| Flux Kontext Dev | Yes | No |
In Create, when Match reference is selected, the picker lists only the models that support it. On the canvas, Match reference is unavailable while the node uses Flux Kontext Dev.
Where does the relit image go?
Section titled “Where does the relit image go?”Selecting Generate adds a model node to the current Level and runs it. Each result is kept as a take and shown in Results. Nodespell stores the full lighting setup with the node, so selecting it later restores the method, preset, and lights. If a result holds lighting settings the node no longer has, Relight offers Restore to node, which writes them back without running anything.
Common problems
Section titled “Common problems”| Problem | What to do |
|---|---|
| “Choose a lighting reference image.” | Add an image under Lighting reference, or switch to Design lighting. |
| “Choose a reference-capable model to match a lighting reference.” | Pick a model marked Yes for Match reference above. |
| “Match reference needs two local image slots. Disconnect the source input before generating.” | The source comes from a connection. Disconnect it and choose the source image in the tool. |
| The subject changes more than the light | Add a preservation note in Lighting notes, such as what must stay unchanged, or try another model. |
Frequently asked questions
Section titled “Frequently asked questions”How many lights can Relight use?
Section titled “How many lights can Relight use?”Up to three: a key light, a fill light, and a rim light. The key light is always present.
Is the Relight 3D stage a real render?
Section titled “Is the Relight 3D stage a real render?”No. The stage shows where your lights are. The AI model reads the setup as instructions and paints the new lighting; it does not ray-trace the scene.
Can I relight using another photo’s lighting?
Section titled “Can I relight using another photo’s lighting?”Yes. Set Relight method to Match reference, add the photo under Lighting reference, and choose a Reference influence.
Does Relight change my original image?
Section titled “Does Relight change my original image?”No. The relit image is a new take on a new node. The source stays unchanged.
