4K Cinematic Upscale (Identity-Preserving Enhancement Prompt)

Ultra-high-resolution 4K upscale with absolute fidelity to the reference image. Preserve facial anatomy, identity, expression, pose, camera angle, framing, clothing, and background exactly as is — zero structural changes. Enhance fine detail naturally (pores, hair strands, eyelashes, fabric texture) with controlled sharpening and high-frequency reconstruction. Remove noise and compression artifacts without smoothing or plastic skin. Maintain accurate skin tones, white balance, and original color relationships. Apply a warm cinematic look with a strong golden back rim light creating a subtle halo around hair and shoulders, plus soft balanced frontal light for clear facial exposure. Introduce natural shallow depth of field while keeping background structure intact. Rich amber and gold tones with realistic daytime ambient light. Negative constraints: no warping, no facial drift, no anatomy changes, no distortions, no perspective shift, no stylization, no hallucinated detail. Output must match the reference exactly — only sharper, clearer, and higher resolution with cinematic warmth.
