Objective: Perform an ultra-high-resolution (4K) photorealistic enhancement and detail reconstruction of the provided reference image.
Fidelity Mandate (Absolute Constraint): Maintain absolute fidelity to the original image. All facial anatomy, proportions, identity, expression, gaze, pose, camera angle, framing, and perspective must be preserved with zero deviation.
Structural Preservation: Clothing, hair, skin structure, background elements, and all physical boundaries must remain unchanged in their structure, placement, and design.
Detail Reconstruction: Recover and enhance fine-grain detail with extreme natural realism. This enhancement must focus exclusively on textural fidelity, including:
- Pores, fine lines, and subtle wrinkles.
- Individual hair strands and eyelashes.
- Fabric weave, seams, and material edges.
Photometric and Lighting Control:
- Color Science: Maintain the original color science, white balance, and tonal relationships exactly as captured.
- Lighting: The direction, intensity, contrast, and shadow behavior must match the source image precisely. The enhancement should only improve clarity and expand the dynamic range, without introducing new light sources or relighting.
Technical Refinement:
- Apply controlled sharpening and high-frequency detail reconstruction.
- Remove all compression artifacts and noise while retaining authentic, natural texture.
- Strictly avoid any smoothing, plastic skin effects, or artificial gloss.
Negative Constraints (Strictly Forbidden):
- No warping, facial drift, or perspective shift.
- No added or missing anatomy.
- No distortion of hands or features.
- No stylization, artistic interpretation, or stylized rendering.
- No hallucinated detail.
- No text or graphics.
Final Output Requirement: The result must be a true-to-life, photorealistic upscale that matches the reference exactly, achieving only clearer, sharper, and higher resolution detail.
Original prompt (before our improvements)
"Ultra-high-resolution 4K enhancement based strictly on the provided reference image. Absolute fidelity to original facial anatomy, proportions, and identity. Preserve expression, gaze, pose, camera angle, framing, and perspective with zero deviation. Clothing, hair, skin, and background elements must remain unchanged in structure, placement, and design. Recover fine-grain detail with natural realism. Enhance pores, fine lines, hair strands, eyelashes, fabric weave, seams, and material edges without introducing stylization. Maintain original color science, white balance, and tonal relationships exactly as captured. Lighting direction, intensity, contrast, and shadow behavior must match the source image precisely, with only improved clarity and expanded dynamic range. No relighting, no reshaping. Remove any grain. Apply controlled sharpening and high-frequency detail reconstruction. Remove compression artifacts and noise while retaining authentic texture. No smoothing, no plastic skin, no artificial gloss. Facial features must remain consistent across the entire image with coherent anatomy and clean, stable edges. Negative constraints: no warping, no facial drift, no added or missing anatomy, no altered hands, no distortions, no perspective shift, no text or graphics, no hallucinated detail, no stylized rendering. Output must read as a true-to-life, photorealistic upscale that matches the reference exactly, only clearer, sharper, and higher resolution."
