Outpainting
Extending a picture beyond its edges.
In plain words
Outpainting is inpainting outward: you add empty canvas around the picture and let the model fill it so that it continues the scene. A square portrait becomes a wide landscape; a tight crop gets its surroundings back.
Where you meet it in a graph
Load Image → Pad Image for Outpainting (ImagePadForOutpaint: left, top, right, bottom in pixels, and feathering) gives a larger IMAGE and a MASK covering the new area. Then any inpainting way from Inpainting and masks: VAE Encode (for Inpainting), or InpaintModelConditioning with an inpainting model, or Flux.1 Fill dev, which handles outpainting especially well.
Values and what they change
- Extend by a moderate amount at a time (a few hundred pixels); very wide extensions repeat or lose the style.
feathering(about 40 to 100) blends the seam.- Keep the result's total size near the family's trained size.
- The prompt describes the whole new picture, not only the added part.
Typical mistakes
- A visible seam: too little feathering or a hard mask.
- Denoise below 1 with VAE Encode (for Inpainting): the new area stays grey.
- Huge padding on a plain model: repeated objects and a style that drifts.
