Before You Generate

Note 1

Start with a sharp reference image. This prompt is written to preserve source identity, silhouette, or product structure before stylization.

Note 2

Use 3:4 on the first run, then test alternate crops after the base composition is working.

Note 3

This prompt suppresses text or logos. Remove that constraint before asking for branded packaging, typography, or visible watermarks.

Best For

  • Portrait studies, beauty concepts, and tightly framed editorial references.
  • Reference-image workflows where identity, product shape, or silhouette should survive the restyle.
  • Clean studio results where spacing, surfaces, and product separation need to read immediately.

Skip This Prompt If

  • You need a wide environment shot or multiple subjects competing for attention in the same frame.
  • You need to begin with a radically different crop than 3:4 instead of honoring the existing composition hints.
  • Your reference image is low-resolution, badly lit, or cluttered enough to break subject preservation.

Mistakes to Avoid

  • Ignoring the recommended 3:4 crop on the first run. The prompt's composition cues were written for that frame.
  • Using a muddy reference image and expecting the prompt to repair identity, silhouette, or packaging structure on its own.
  • Asking for readable type, logos, or packaging text without first removing the no-text constraint.
