Premium realistic underwater studio product photograph, 3:2 landscape. One physical immersion-rated waterproof backpack, matte cobalt TPU-coated fabric with welded seams, securely rolled and buckled watertight closure, tangerine shoulder straps and plain orange hardware. Fully submerged in clear water, its rounded base resting on a clean slate-blue tank floor in the right half of the frame. Rear three-quarter view at low camera height reveals both shoulder straps, gently lifted into loose arcs by the water; the main body remains the clear focal point. Broad cool upper-left illumination, deep blue shadow falloff and a restrained warm edge highlight. Subtle refracted light bands, sparse tiny bubbles along the strap edges, believable fabric folds and matte material response. Entire backpack sharply resolved, generous empty water to the left, tank edges and supports outside the frame. Real photographic finish, no CGI gloss. No people, marine animals, electronics, clutter, text, logos or watermarks.
