Background edit

The Background edit mode changes the visual context of a photo while keeping the result believable. It now includes two distinct workflows inside the same mode:

• Classic: mainly replaces or restyles the background while trying to preserve the subject.
• Palette: recolors the entire image inside a controlled 3-6 color palette, then rebuilds the background either as a uniform backdrop or as a new setting.

If you want to change scene, atmosphere, lighting, or art direction without starting with surgical local edits, this is the right mode.

Use Background edit when:

• you want to move the subject into a new environment;
• you want to simplify or clean up a busy background;
• you want a more art-directed result while keeping the original photo as the base;
• you want strict color direction through a limited palette;
• you want multiple background concepts from the same source image.

• If you need to change subject details, outfit, face, product details, or specific regions: use Single image edit.
• If you only want to relight the existing scene without changing its layout: use Relight.
• If you need restoration, scratch removal, or conservative colorization: use Restore photo.
• If you mainly want more sharpness or quality without changing the scene: use Enhance photo quality.

The Classic workflow is the closest to the old “background only” experience:

• describe the background and lighting;
• use the Background Builder and, if needed, a short prompt;
• the model tries to keep the subject stable while rebuilding the background.

It is great for:

• studio, interior, and realistic location swaps;
• background cleanup;
• atmosphere changes without a hard palette constraint.

The Palette workflow is more directive:

• choose or extract a palette of 3 to 6 colors;
• the palette is applied to subject, light, props, atmosphere, and background;
• then choose whether the final output should end as:
  • a uniform backdrop, or
  • a new setting.

This workflow is ideal for:

• brand-consistent visuals;
• tightly controlled color concepts;
• editorial, poster-like, or highly art-directed scenes;
• outputs where atmosphere and color grade must stay inside a narrow range.

• 1 source image.
• Depending on the workflow:
  • Classic: a background and/or lighting description via Builder or prompt.
  • Palette: a manual palette or a dedicated reference image to extract colors from.
• Optional:
  • markup, if you want visual instructions;
  • Control Map, if you want tighter structure and depth guidance.

When you start the job, the app sends:

• the source photo;
• a structured promptSpec for background mode;
• optional markup;
• optional Control Map.

The backend builds a prompt that tells the model to:

• replace or restyle the background;
• preserve identity, pose, framing, and key subject details;
• realign lighting, shadows, perspective, depth, and reflections.

The backend builds a more constrained prompt that includes:

• the exact palette colors;
• a strict instruction to stay inside that palette;
• the selected background treatment:
  • uniform backdrop, or
  • new setting;
• an optional scene description;
• your optional note.

Important: in Palette, the task is not “change only the background”. The model is instructed to recolor the whole image into the palette and then rebuild the background using the selected treatment.

In this mode you will typically see:

• Mode: set to Background edit.
• Background workflow: choose between Classic and Palette.
• Image upload: the main source photo.
• Background Builder: available in the classic workflow.
• Palette colors: available in the palette workflow, with color picker + HEX input.
• Reference image: a dedicated uploader for palette extraction.
• Palette proposals: suggestions such as Dominant 3, Balanced 5, and Extended 6.
• Background output: choose uniform backdrop or new setting.
• Prompt / optional note: extra details.
• Markup: optional visual guidance.
• Control Map: optional geometry guidance.
• Change background: start the edit.
• Generate variants: produce alternatives.
• Use as input: run a second pass from the result.

1. Upload the photo.
2. Keep the workflow on Classic.
3. Set background and light with the Background Builder.
4. Add a short prompt only if needed.
5. Generate.
6. If needed, make variants or run a second pass.

1. Upload the photo.
2. Switch the workflow to Palette.
3. Build the palette manually or upload a reference image.
4. Extract palette proposals and apply the best one.
5. Choose uniform backdrop or new setting.
6. Add only a short note if needed.
7. Generate and compare variants.

In the main selector, choose Background edit.

For best results:

• use sharp images;
• avoid strong motion blur;
• use a photo where the subject is clearly separated from the background.

Use the Background Builder to define:

• background: where the subject should go;
• lighting: light type, direction, and mood.

Examples:

• “minimal photo studio”
• “warm cozy cafe”
• “night street with neon”
• “soft softbox lighting”
• “side golden-hour lighting”

You can build the palette in two ways:

For each slot you can:

• open the color wheel;
• type or refine the HEX code;
• add or remove colors, staying between 3 and 6.

Upload a dedicated reference image in the reference panel. This image:

• is only used to sample colors;
• is analyzed locally;
• is not used as the main image being edited.

Then click Extract palette proposals. The app may suggest multiple variants:

• Dominant 3
• Balanced 5
• Extended 6

Apply the version you prefer with one click.

Use one of the selected palette colors as a clean, controlled background.

Best for:

• graphic portraits;
• branded visuals;
• creative e-commerce;
• outputs that need very tight color discipline.

Describe the setting you want, for example:

• “refined hotel lobby”
• “brutalist showroom”
• “rainy neon street”

In this case, the scene description guides structure, materials, and mood, but the colors still have to stay inside the selected palette.

The prompt can describe:

• constraints;
• atmosphere;
• lighting and shadow coherence;
• what must not change.

Examples:

• “keep face and outfit unchanged”
• “soft shadows consistent with the new light”
• “no text, no watermark”

The note should not restate the whole task. Use it to refine:

• facial naturalness;
• shadow behavior;
• color priority;
• textures or materials to preserve.

Examples:

• “keep facial features natural”
• “use the darkest color for shadows and depth”
• “preserve the original fabric texture”

Markup is useful when you want to:

• point to a critical area visually;
• show where the subject edge must stay cleaner;
• indicate regions that should be preserved or blended more carefully.

Use Canny or Depth when you want to:

• keep scene structure more stable;
• guide perspective and layering more tightly;
• reduce excessive drift from the original layout.

Click Change background and evaluate:

• overall believability;
• edge quality;
• lighting and shadows;
• color coherence;
• fidelity to the scene or to the palette.

• If you want exploration: use Generate variants.
• If the result is close: use Use as input and ask only for refinement.

Use a simple structure:

background + lighting + subject constraint + realism note

Example:

“Replace the background with an elegant editorial studio. Soft side light from the left. Keep the subject identical. Realistic shadows and clean edges.”

Use an even lighter structure:

scene/backdrop + color-priority note + quality constraint

Example:

“New minimal showroom setting. The darkest color should drive shadows and depth. Keep textures and facial features natural.”

• In Classic, the system is optimized to keep the subject as stable as possible.
• In Palette, the whole image may be recolored: subject, atmosphere, props, and background.
• The reference image used to extract the palette is separate from the main photo.
• In Palette + new setting, the model is strongly guided by the palette, but it is still model-driven. If you want tighter control:
  • narrow the palette to 3-4 colors;
  • make the scene description shorter;
  • also try the uniform backdrop option.

• In Classic: add stronger constraints for face, pose, outfit, and identity.
• In Palette: remember that the subject may be recolored. If you want a softer effect, choose a palette closer to the original image.

• Reduce the palette to 3-4 more distinct colors.
• Use a less material-heavy or color-loaded scene description.
• Try the uniform backdrop option.
• Generate variants: a second or third result often follows the palette better.

• Simplify the scene.
• Ask for realism, natural textures, and coherent details.
• Avoid too many fantasy elements in one pass.

• Use Use as input and ask for edge cleanup.
• Add markup to critical areas.
• If you need strong local control, refine afterward in Single image edit.

• In Classic: describe direction and intensity more clearly.
• In Palette: make sure the palette includes a strong shadow color and a believable highlight color.

Choose Classic when you mainly want a believable new background and a stable subject.

Choose Palette when you want real control over the color direction of the whole image, with a more art-directed and professional workflow.
