Ultra Realistic 4K Image Upscaling

Enhance and upscale the uploaded image to an ultra-high-resolution, highly detailed photographic result. Preserve the exact subject identity, face, clothing, pose, proportions, background structure, and original composition. Recover and improve fine details such as eyes, hair strands, skin texture, fabric patterns, edges, small objects, and environmental elements without inventing unnecessary details. Remove compression artifacts, pixelation, blur, noise, and unwanted softness while keeping the image natural. Maintain realistic lighting, shadows, colors, and perspective. Do not alter the person's facial identity or make the image look artificially sharpened. The final result should have clean, crisp, professional 4K-quality photographic detail.
