Woven Light Underwater

Premium realistic studio product photograph, landscape 4:3. One unbranded slate-blue waffle-weave microfiber swim towel, neatly folded into a low rectangular stack, fully submerged and resting on the pale blue floor of a clean-water tank. Position it in the left half with generous empty water to the right. Low three-quarter camera angle through the tank glass; no visible tank edges or waterline. A narrow amber projection from upper left crosses the folded top and front edge, revealing crisp woven cells, stitched hems and softened wet folds. Cool blue fill, believable underwater refraction, restrained caustics on the floor, a few tiny trapped bubbles along the stitching. The saturated fabric rests naturally without floating. Contemporary magazine art direction, realistic matte wet textile, controlled highlights, sharp product detail and gently receding background. No people, marine animals, props, text, logos or watermarks. No CGI gloss.
