Create an ultra-realistic 4K image in a 1:1 square format featuring the inserted product displayed exactly as it exists in real life, maintaining full accuracy in shape, proportions, materials, colors, and all printed or engraved details such as logos or text, which must remain perfectly sharp, correctly spelled, and physically integrated. Present the product as a luxury hero shot centered in the frame, captured at a close-up angle slightly above eye level with a short focal length to emphasize dimensionality and reflection. The product should rest on a clean, dark gradient surface transitioning from deep charcoal at the edges to a subtle indigo-blue highlight near the center, creating depth and contrast. Use controlled studio lighting from the upper left direction at a neutral temperature around 4700K, producing smooth specular reflections and a luminous highlight along metallic or glossy surfaces. Include a soft fill light from the front-right side to enhance visibility and define contours without flattening textures. Shadows should be clean, diffused, and directionally accurate, softly fading into the background with no hard edges. Ensure that reflections beneath the product are subtle and physically consistent with the surface gloss, appearing slightly blurred with a gentle fade. The overall atmosphere must convey premium quality, clarity, and precision with no visible noise or artifacts. The result should capture realistic depth, perfect exposure balance, and rich contrast between warm highlights and cool background tones for an elegant, high-end appearance.
