How to Get Great Results
- Step 1
Start with a strong base image
Pick a source image with good lighting and composition. HiDream Dev excels at refining, not reinventing.
- Step 2
Write targeted edit prompts
Describe the change and the anchor to keep: 'add frost runes to the sword, keep the face and lighting unchanged'.
- Step 3
Iterate in small steps
Make one change per pass (gear, color grade, background accent) to avoid drifting likeness.
- Step 4
Use concise negatives
If artifacts appear, add short negatives like 'no blur, no glow halos, no extra fingers'.
Example Prompts
Add glowing frost runes to the sword; keep pose, face, and outfit unchanged
Replace the leather cloak with dark green velvet, subtle sheen; keep lighting and framing identical
Increase weathering on the armor edges and add soot to gloves; preserve skin and hair detail
Swap the background to a moody studio gray gradient; keep subject colors and contrast consistent
Add a silver filigree pattern to the pauldron; do not alter facial features
