Premium editorial campaign photograph for a contemporary environmental health brand. A single thin-walled cylindrical drinking glass filled with perfectly transparent water, beside a small unmarked capped laboratory water-sampling vial, arranged with precise asymmetrical spacing on a seamless matte white surface. Close three-quarter viewpoint, objects fill most of the vertical composition. Strong controlled daylight from the upper left creates intricate optical caustics and long crisp shadows. A translucent mineral-green glass panel outside the frame casts a subtle green reflection across the background, while the water itself remains completely colorless. Extraordinary realism in the glass edges, meniscus, refraction and surface texture. Restrained, clinical, quietly intriguing, sophisticated still-life art direction, medium-format commercial photography, generous clean margins, white and pale celadon palette with deep forest-green shadow accents. --no text, logos, labels, watermarks, bubbles, splashes, plants, people --ar 4:5 --raw --v 8.2
