Промт для восстановления и ретуши студийного портрета в деталях

Restore and enhance this photograph with absolute uniform processing across every pixel. Start with the background: remove all canvas-texture patterns, dust spots, and vertical scratches from the mottled, soft-focus studio backdrop. Sharpen the background elements and tonal gradients to be as clear and defined as the subjects. Restore the foreground shirts with extreme precision: capture the weave of the fabric, the sharp lines of the collars, the button placket, and the subtle folds in the white material. Apply high-fidelity sharpening to the clothing fibers to match face detail exactly. Address all edges and corners: remove the physical wear, white surface chips, and corner indentations, ensuring the very edges of the frame are as crisp and clean as the center. For the subjects: remove the dark spots and scratches from the hair and skin while maintaining natural texture. Maintain the original warm sepia-toned black and white palette and flat-film depth of field—everything must be in sharp focus with no artificial background blur. 

CRITICAL: Apply IDENTICAL sharpness and restoration quality to background, clothing, and faces—no hierarchy. Background textures must be as sharp and detailed as any face. Clothing textures (fabric weave, collars) must be restored with full micro-detail. WARNING: You have a natural bias toward faces. Consciously COMPENSATE for this by applying extra restoration effort and high-frequency sharpening to the background and clothing to ensure the final image is uniformly sharp from edge to edge. At no point should the faces appear "over-restored" compared to the shirts or the backdrop.

ANTI-BIAS ALERT: You naturally focus restoration/colorization on FACES while leaving background, clothing, and foreground under-processed. This is the #1 quality failure. Consciously counteract this.

MANDATORY UNIFORM QUALITY CHECK:
- Background sharpness = Face sharpness (NOT less)
- Clothing detail = Face detail (fabric weave, buttons fully visible)
- Foreground objects = Faces (flowers, grass, objects NOT blurry)
- Edges/corners = Center of image (NOT softer or less restored)
Any area less sharp or colorized than faces is a FAILURE — redo that area.

ABSOLUTE RULES — NEVER VIOLATE:
- YOU ARE RESTORING/COLORIZING AN EXISTING PHOTO — not generating a new one. Every pixel must correspond to the original image.
- DO NOT recreate, reimagine, or regenerate any part of the scene — work only with what is already in the photo
- DO NOT add, invent, or hallucinate any part of the image that is not in the original
- DO NOT change the framing or composition — keep it exactly the same
- DO NOT add any new damage, folds, creases, tears, dark borders, vignettes, or artifacts
- DO NOT change, replace, or alter any person's face, body, or identity
- DO NOT add or remove any person or object
- DO NOT modernize clothing, hairstyles, or any visual elements
- Keep the exact same framing, crop, and aspect ratio as the original
- SKIN COLOR: Eastern European skin = warm-neutral to cool-neutral, medium tone. NEVER red or orange. NEVER ghostly pale or washed-out. NEVER airbrushed or plastic. DO NOT add acne, spots or marks not in the original
- COLOR SATURATION: Keep overall saturation MODERATE — natural analog film look. NOT vivid digital. NOT pale or desaturated`
- CRITICAL: Preserve original tonal character EXACTLY — black and white photos MUST stay black and white. Sepia photos MUST stay sepia. DO NOT add ANY color whatsoever.
- OUTPUT MUST BE GRAYSCALE if the input is grayscale — no warm tones, no blue tints, no color cast of any kind
- Apply uniform sharpness to the ENTIRE image — background and foreground equally. NO background blur
- DO NOT smooth, airbrush, or beautify faces — preserve natural skin texture exactly as in the original
