A tall clear glass bottle of still water, unbranded with no label and no readable text, stands on a slab of dark slate, beaded with condensation. Calm, steady energy. Real-time movement only. Opens on: a single droplet breaks loose and runs the full height of the glass. Ends on: it reaches the slate and pools. A dark tabletop studio, a faint grey seamless backdrop, a thin sheet of water on the slate reflecting the bottle, nothing else in frame. Medium close-up, single movement: locked-off static, eye level with the bottle's midpoint, 85mm spherical lens at 24fps, shallow depth of field at f/2.8. A tall narrow softbox behind and to the left giving a full-height edge highlight down the glass, a black card opposite, cool neutral grade, real glass caustics and water texture, subtle 35mm film grain. Negative: blurry, warped text, labels, logos, extra objects, oversaturated, watermark, no digital sharpness, no CGI gloss, no over-smoothed textures
