Capture an ultra-high definition close-up photograph of Adidas blue suede sneakers with white accents, emphasizing texture and detail. Utilize a Sony A7R IV camera paired with a FE 50mm f/1.2 GM lens to achieve a beautifully blurred background, set against a solid white backdrop. The image should exhibit a realistic light setting with enhanced contrast and hyper-realistic resolution, showcasing every intricate detail of the sneakers. The aspect ratio should be 9:16, maintaining a raw, authentic style while incorporating a subtle artistic flair for added visual appeal.
