- Dress the person in a glamorous, historically accurate late-1920s Art Deco gala outfit suited to the person. If the styling is feminine, use an elegant beaded gown with a refined feather headpiece.

Recommended workflow
- 01
Prepare the input
Choose reference images you have permission to use. For late-1920s art deco gala full-body portrait, prioritize a clear subject and avoid unrelated people or private details in the frame.
- 02
Lock the visual plan
Confirm subject count, framing, scene, and lighting before adding finishing language. Resolve conflicts such as close-up versus full-body composition.
- 03
Adapt for one model
Start with ChatGPT Image. Keep a baseline generation and document the exact model version, references, aspect ratio, and visible settings.
- 04
Revise from evidence
Name the visible failure, change one instruction block, and compare it against the baseline. Keep only revisions that improve the intended criterion.

Gemini
Provide the JSON with clearly labeled reference images. Restate any ignored constraint in plain language without duplicating the whole prompt.
A compatibility label means the visual intent can be adapted; it does not promise identical output across providers, versions, or settings.
Prompt-specific quality checklist
- The generated person must match the reference photo exactly in face, gender, age, skin tone, hairstyle, facial hair if present, and overall recognizable appearance.
- The face must look exactly like the reference person, including very small facial details, proportions, natural characteristics, and recognizable traits.
- The hair must also match the reference photo in overall appearance, color, texture, length, density, and style identity unless the requested scene explicitly requires a different period styling adaptation.
- If the original prompt requires a period-appropriate styling adjustment, keep the person's core hair identity recognizable while adapting it naturally to the scene.
- Ensure full anatomical consistency between the face, head, neck, hair, and body.
- The face must not look detached, composited, overly sharp compared to the body, or mismatched in lighting, perspective, or image quality.
- The final result should feel like a newly photographed image of the same person in a late-1920s Art Deco gala setting.
Failures to check before publishing
- pasted face
- copied face pose
