Ultra-realistic, 50mm, f/2.8 avant-garde food photography capturing a single tuna eyeball. Rendered with an exceptionally semi-translucent, clear central structure and delicate iris, appearing clean and refined, surrounded by ivory fish flakes. Michelin-star modern fusion plating on an abstract-shaped, matte grey ceramic dish resembling crumpled metal. Garnished with foam of umami-infused kombu, finely chopped black truffle, and a delicate gold leaf accent. Subject is positioned off-center for visual balance. Paired with a chilled, elegant glass flute of sparkling Junmai Sake (or Champagne), showing clear effervescence and tiny bubbles. Background is a sophisticated, contemporary dining space with reflective metallic surfaces and soft ambient LED lighting, gently blurred. Cinematic clarity, crisp reflections, polished, avant-garde feel. Soft, high-end side-lighting.
