Premium realistic underwater studio product photograph, portrait 3:4. One long, slender brushed-stainless-steel vacuum thermos with a securely tightened, gasketed matte-black screw cap, no handle, fully submerged in clean water. It rests horizontally on a smooth slate-grey tank platform, running diagonally through the lower half from bottom left toward upper right. Photograph directly overhead through an optical tank window; generous empty space above. Broad cool-white light from the right creates a luminous steel edge and falls into deep blue-grey shadow on the left, evoking storm-cloud contrast without clouds or murky water. Clearly resolved cylindrical construction, subtle brushed metal grain, believable underwater refraction, restrained caustics across the platform, and a few pin-sized bubbles attached at the cap seam. Contemporary magazine styling, realistic materials, no synthetic CGI gloss. No people, marine animals, clutter, text, logos or watermarks.
