Create an ultra-realistic 4K underwater product photo in a dramatic cinematic style. Use the uploaded image of Uploaded photo exactly as it is — preserve all details: shape, proportions, materials, logos, label text, textures, and colors. Do not alter, beautify, retouch, redraw, crop, or retype any part of the product. The product must be shown pixel-identical and 100% legible.
Pose and composition:
Place the product floating underwater at a strong diagonal angle (bottom-right to top-left), slightly tilted in depth (not fully flat), with the label visible in a natural three-quarter perspective. Do not center the product — position it off-center with generous negative space in the top-left area of the frame. Scale: approximately 30% of image height.
Include a clearly visible water surface at the top with soft wave distortion and highlights. Create narrow, directional underwater god rays from the top-right corner, with high contrast between light shafts and darker water. Use a deep marine-blue background with a cyan glow where the rays hit. No background objects.
Add medium to high density of air bubbles in different sizes. Cluster them unevenly along the product’s sides and neck — avoid symmetry. Bubbles must have natural deformation, bright light edges, darker inner volume, and realistic optical distortion. Include small bubbles breaking off in multiple directions. A few bubbles may contain tiny warped reflections of the product.
Main light from above and behind (top-right) to create strong rim lighting, visible specular highlights on edges, and bright reflections in transparent or glossy areas. Add subtle fill light from front-left to illuminate label or branding without flattening the shadows. No hard shadows on the background — use soft atmospheric falloff in water.
Glass, metal, plastic, or ceramic must reflect and refract the underwater environment realistically. Preserve gloss, texture, and edge sharpness. If the product is transparent, emphasize inner reflections, refraction distortions, and thickness. If metallic, show controlled highlights and no blown areas. Label must remain matte or satin, flat and sharp, with all text fully readable.
Slight upward underwater angle (~15–20 degrees). Focal length ~70 mm. Aperture f/11 for sharp focus on product, with slightly blurred background. Use fast shutter or strobe to freeze bubbles and detail. Depth of field must be shallow enough to create separation from background, but deep enough to keep the product edges sharp.
High contrast, rich deep blues, clean cyans in light shafts. Use strong midtone separation and realistic underwater haze. Apply an S-curve contrast profile — deep shadows, crisp highlights, no clipping or bloom. No color shifts in the product.

Render at 4000 px or higher. No upscaling. No watermarks or overlays.
Do not center the product. Do not make it vertical or symmetrical. No flat or even bubble distribution. No fake or generated label text. No font substitution. No fisheye lens or wide-angle distortion. No soft glow, fog or blur over the product. No background particles, fish, or light flares. No logo replacements.
