プロンプトUsing the supplied head-and-shoulders portrait as the primary source, create three distinct edited variants optimized for use in a book. Follow these general instructions for all variants: crop to a 4:5 portrait composition with the eyes on the upper third; preserve the subject’s facial proportions and expression exactly; perform gentle, natural skin retouching (remove blemishes and stray hairs but keep real skin texture and pores); clean and refine hair edges (especially around bangs and loose strands) and add a subtle rim/hair light to separate the subject from the dark background; slightly reduce the saturation and visual prominence of the light-blue sweater to keep focus on the face; apply a soft vignette and a delicate film grain; enhance local sharpness on the eyes and eyelashes; maintain original lighting direction and overall mood; do not alter anatomy or change facial features.
Variant A — Warm Poetic (Color, Sepia-tinged):
- Warm, muted color grade with a gentle sepia wash and subdued midtone warmth; slightly desaturate cool blue tones.
- Strengthen a soft amber side fill from the left to enhance three-dimensionality; keep shadows soft and natural.
- Add a small, tasteful feather hairpin near the right temple (subtle ivory/gold feather, integrated naturally into the hair with correct shadowing and scale).
- Keep background dark and unobtrusive; add a faint warm glow behind the head for separation.
Variant B — Classic Poet (Black & White, Film Look):
- Convert to high-quality black & white with film-style contrast: deeper blacks, rich midtones, and a delicate highlight roll-off.
- Add prominent but natural film grain and a subtle paper texture overlay in the background (very faint, not distracting).
- Emphasize eyes and eyelashes via local contrast and dodge/burn; maintain natural skin texture.
Variant C — Author at Work (Color, With Prop):
- Based on Variant A color grading (warm, muted sepia-tinge) but include a subtle prop to suggest book-making: a partially visible closed or slightly open book/manuscript at the lower-right foreground, ensuring it does not occlude the face.
- Integrate a natural-looking hand (same skin tone) resting lightly on or near the book’s edge; match perspective, lighting and shadow so the prop reads as part of the original scene.
- Keep all retouching and hair refinements the same as Variant A, and slightly mute sweater color further if the prop introduces additional color.
Deliverables and technical requirements:
- For each variant produce two output sizes: a web-ready JPEG (sRGB) optimized at approximately 2000 px on the long edge, and a print-ready high-resolution file suitable for professional printing at 300 DPI with the long edge between 3000–3500 px (TIFF or high-quality JPEG). Label each output clearly by variant and size.
- Keep all edits natural and non-destructive to the subject’s identity. Provide the edited files cropped to 4:5 and also include a full-crop version (original aspect) for internal use.
- Note any areas where manual mask refinement may be needed (hair edges, hand/prop seams) so they can be quickly adjusted if needed.
Do not change facial features, expression, or overall head tilt. Respect the portrait’s original mood and produce elegant, book-ready results.
