A Glass of Water and a Sampling Vial in Cool Celadon

Medium-format commercial photography, a premium editorial campaign image for a contemporary environmental health brand. Strong, controlled daylight enters from the upper left, producing intricate optical caustics and long crisp shadows. On a seamless matte white surface, a lone thin-walled cylindrical glass holds perfectly transparent water; next to it stands a small capped laboratory water-sampling vial with no markings, the two placed with precise asymmetrical spacing. Frame it as a close three-quarter view with the objects filling most of the vertical composition. Outside the frame, a translucent mineral-green glass panel lays a subtle green reflection across the background, but the water itself remains totally colorless. Render the glass edges, meniscus, refraction and surface texture with extraordinary realism. Restrained, clinical, quietly intriguing, sophisticated still-life art direction; generous clean margins; a white and pale celadon palette with deep forest-green accents in the shadows. --no text, logos, labels, watermarks, bubbles, splashes, plants, people --ar 4:5 --raw --v 8.2
