Inpainting mask & prompt guide
Inpainting replaces a masked region of an image with new content — fixing a hand, swapping an object, removing a distraction. The hard part isn’t the mask, it’s getting the new pixels to blend instead of looking pasted on. This guide turns your “what’s there / what I want” description into a tailored prompt and the right denoising strength.
How it works
Two things govern an inpaint: the prompt for the masked region and the denoising strength. The prompt should describe what you want plus enough of the surrounding scene’s lighting and style for the result to harmonise. Denoising controls how aggressively the area changes — low for subtle fixes, high for full replacements. This tool combines your inputs into a prompt that explicitly asks for a seamless blend and recommends a denoise band based on how big your change is and which model you’re using.
Tips and notes
- Match the light. Always tell the model the scene’s lighting direction and warmth so the edit doesn’t glow differently from its surroundings.
- Feather and oversize the mask. A slightly larger, soft-edged mask gives the model context to blend into and kills hard seams.
- Step the denoise. Start lower than you think; raise it only if the change isn’t strong enough. High denoise on a small mask invites artefacts.
- Iterate the region, not the whole image. Re-run just the mask with small prompt tweaks rather than regenerating everything.
