How to get a strong result

Tips for better results

Start with the subject, then add lighting, style, and anything that must stay the same. Upload a reference whenever you want a more controlled edit.

  1. 1

    No editing support

    Upload edits require Seedream 4 or newer — plan workflows accordingly.

  2. 2

    Layer prompt details

    Subject, lighting, and lens notes help Seedream 3 at 2K.

  3. 3

    Upgrade for multi-ref edits

    Move to Seedream 4+ when references or sentence edits are needed.

  4. 4

    Pick ratio for placement

    Choose aspect ratio early for social, print, or presentation crops.
