Sharpen Face Detail

ROLE

Act as a senior professional photo retoucher, restoration specialist, photographer and AI image-editing specialist. Perform a controlled, production-quality facial detail enhancement of the uploaded image.

Treat the source image as the absolute visual ground truth. This is an enhancement task, not a face reconstruction, beautification or redesign.

EDIT

Improve the visible clarity, focus and fine detail of the subject’s face while preserving the exact person.

Reduce mild facial softness or blur and recover naturally supported detail from the existing image. Enhance facial detail selectively, especially around the eyes, eyelashes, eyebrows, lips, facial hair when present, hairline and other naturally defined edges.

Improve skin clarity while preserving realistic pores, fine texture, subtle tonal variation and natural imperfections.

Do not generate a different face or invent facial information that is not reasonably supported by the source image.

PRIMARY OBJECTIVE

Make the face appear as though it had originally been captured with slightly better focus, optical sharpness and image quality.

The improvement should be clearly noticeable when comparing before and after, while still looking like the exact same photograph of the exact same person.

The result must remain photographic rather than appearing AI-enhanced, reconstructed, oversharpened or digitally painted.

FACIAL DETAIL ENHANCEMENT

Prioritize enhancement of:

* eyes and natural iris definition where genuinely visible;
* eyelashes and eyelid boundaries;
* eyebrow hairs;
* lips and natural lip texture;
* facial hair and individual beard or moustache hairs when present;
* hairline and visible individual hair strands;
* nostril and nose-edge definition;
* natural facial contours;
* pores and believable skin microtexture.

Restore clarity through controlled local detail enhancement rather than aggressive global sharpening.

Preserve naturally soft areas where the original depth of field or optical characteristics require them to remain soft.

Do not sharpen every facial region equally.

IDENTITY LOCK

Preserve the subject’s recognizable identity exactly.

The following must remain structurally unchanged:

* head and face shape;
* eye shape, size, spacing and direction;
* eyebrows and their natural shape;
* nose shape and proportions;
* lips and mouth shape;
* teeth when visible;
* ears;
* jawline and chin;
* cheek structure;
* hairline;
* expression;
* natural facial asymmetry;
* apparent age;
* skin tone;
* distinguishing features such as freckles, moles, scars and facial hair.

Do not beautify, idealize, reshape, symmetrize or reinterpret the face.

Do not make the eyes larger or brighter, reshape the nose, enlarge the lips, strengthen the jawline, smooth wrinkles, remove natural imperfections or otherwise modify facial attractiveness.

DETAIL RECOVERY LIMIT

Recover only detail that is visually plausible from the source.

If a feature is genuinely unresolved because of severe blur, obstruction, extreme compression, clipping or insufficient resolution, improve its appearance conservatively rather than inventing precise new anatomy or texture.

Never hallucinate eyelashes, iris patterns, pores, facial hair, teeth or other high-frequency details merely to make the image appear sharper.

The enhancement should look optically plausible.

SKIN PRESERVATION

Preserve authentic skin.

Maintain pores, fine lines, subtle blemishes, natural tonal transitions and realistic texture.

Do not use plastic smoothing, artificial pore patterns, excessive microcontrast, beauty-filter skin, waxy texture or uniform synthetic detail.

Do not make skin unnaturally crisp.

SHARPNESS CONTROL

Apply sharpening selectively to meaningful facial detail.

Avoid:

* excessive edge contrast;
* white or dark sharpening halos;
* crunchy skin;
* HDR-like microcontrast;
* ringing artifacts;
* amplified JPEG artifacts;
* exaggerated pores;
* artificial eyelashes;
* oversharpened hair;
* excessive eye enhancement;
* fake iris detail;
* noise mistaken for texture.

The face should look naturally clearer, not visibly sharpened.

SOURCE PRESERVATION

Do not alter anything that is unrelated to facial clarity.

Preserve the original:

* body and pose;
* hairstyle;
* clothing and accessories;
* background and objects;
* composition and crop;
* camera position and perspective;
* lighting and shadows;
* color balance;
* depth of field;
* image grain and noise character;
* photographic atmosphere.

Do not change the background or globally sharpen the entire photograph unless minimally necessary to maintain natural consistency with the enhanced face.

REALISM & INTEGRATION

Match the enhanced facial detail to the original image's resolution and photographic characteristics.

Preserve the source camera's:

* lens characteristics;
* depth of field;
* focus falloff;
* motion characteristics;
* lighting direction and softness;
* color temperature;
* grain;
* noise;
* compression characteristics.

The enhanced face must not appear significantly higher-resolution than the surrounding hair, body or scene.

Maintain natural transitions between enhanced and untouched areas so there is no visible facial enhancement boundary.

ARTIFACT PREVENTION

Do not introduce:

* altered facial anatomy;
* changed expression;
* changed identity;
* artificial symmetry;
* fake skin texture;
* invented facial features;
* distorted eyes;
* corrupted teeth;
* excessive eye brightness;
* plastic skin;
* sharpening halos;
* ringing;
* oversharpening;
* excessive HDR;
* smeared textures;
* unnatural hair strands;
* mismatched grain;
* inconsistent lighting;
* generative-AI artifacts.

QUALITY CONTROL

Before finalizing, compare the edited face against the source and verify:

1. The face is visibly clearer and better defined.
2. The subject remains unmistakably the same person.
3. Facial geometry and expression have not changed.
4. Enhancement comes primarily from improving existing detail rather than generating new features.
5. Skin remains naturally textured.
6. Eyes, eyelashes, eyebrows, lips and hair remain anatomically faithful to the source.
7. There are no sharpening halos, crunchy textures or synthetic details.
8. The enhanced face remains consistent with the resolution, lighting, grain and depth of field of the original photograph.
9. Everything outside the requested facial-detail enhancement remains faithful to the source.

If stronger sharpening would require inventing facial information or changing identity, prefer slightly less sharpening.

OUTPUT

Return one polished final image only.

Preserve the original aspect ratio, crop, framing and composition.

Use the highest practical output quality while maintaining photographic authenticity.

Do not add captions, text, borders, logos or watermarks.
