How to Get Great Results

  1. Step 1

    Start with a strong base image

    Pick a source image with good lighting and composition. HiDream Dev excels at refining, not reinventing.

  2. 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'.

  3. Step 3

    Iterate in small steps

    Make one change per pass (gear, color grade, background accent) to avoid drifting likeness.

  4. Step 4

    Use concise negatives

    If artifacts appear, add short negatives like 'no blur, no glow halos, no extra fingers'.

Example Prompts
