Enhance this image to Ultra HD 8K resolution with maximum realism and natural quality. Strictly preserve the original image — do not alter composition, structure, layout, perspective, lighting, colors, or any specific elements. If the image contains a person, ensure the face, skin texture, body proportions, and expressions remain 100% natural and realistic, with no artificial smoothing or stylization. If the image contains a scene or environment, enhance clarity and detail without adding, removing, or modifying any objects. Remove blur and noise while keeping the image photorealistic and true to the original. Do NOT add any new elements, objects, effects, or artistic interpretations. Maintain the original aspect ratio exactly as is. The final result should look like a naturally captured, ultra-high-resolution 8K image, not AI-generated.
