How to Get Great Results
- Step 1
Start with a stable base
Pick a source render with the right pose and lighting—Kontext Dev excels at targeted changes, not total overhauls.
- Step 2
Write scoped edit prompts
Say what to change and what to keep: 'replace leather cloak with deep green velvet; keep face, lighting, and background'.
- Step 3
Edit in passes
Make one change per pass (gear swap, color grade, background) to keep likeness and composition stable.
- Step 4
Use concise negatives
If artifacts appear, add short negatives like 'no blur, no halos, no extra fingers'.
Example Prompts
Swap the cloak to forest‑green velvet with subtle sheen; keep pose, face, and lighting unchanged
Add engraved silver filigree to the pauldron; preserve skin and hair detail
Change background to a neutral studio gray gradient; maintain subject colors and contrast
Replace the leather belt with braided rope; keep composition intact
Enhance candle glow and warm grade; avoid shifting wardrobe colors
