Create a hyper-realistic close-up product photography image of a luxurious silk scarf, elegantly draped against a minimalist white background. Use a 100mm macro lens with an aperture of f/2.8 to achieve a shallow depth of field, ensuring the intricate patterns and textures of the fabric are in sharp focus while the background is softly blurred. Set the ISO to 100 and shutter speed to 1/125s to maintain clarity and avoid motion blur. The scarf should feature rich jewel tones, showcasing its sheen and the way light interacts with its surface. Soft, natural light should illuminate the scarf from a window, casting delicate shadows that enhance its three-dimensional quality. The composition should evoke sophistication and elegance, appealing to a high-end fashion audience. In post-production, apply subtle color grading to enrich the hues while maintaining the luxurious feel of the image. Ensure the final output is in ultra-detailed 8K resolution, capturing every thread and fold of the scarf with precision.
