A Jamaican sprinter, late 20s, tight cornrows pulled back, high cheekbones, eyes fixed down the lane, powerful shoulders and thighs, in an unbranded black two-piece race kit, spikes locked into the blocks. Building energy. Opens on: she is coiled in the set position, fingertips on the line, breath held. Ends on: she drives out of the blocks, first stride slamming down, blocks recoiling. 120fps slow motion, played at 24fps. A generic outdoor track at overcast dawn, wet red lanes, empty grandstand soft behind. Medium full shot, single movement: locked-off static, very low angle at track level, 35mm lens, shallow DOF. Overcast diffused light with a hard rim from one low sun break, desaturated cool grade, natural skin texture, 35mm film grain. No logos or text. Negative: blurry, distorted faces, extra fingers, warped text, oversaturated, watermark, no digital sharpness, no CGI gloss, no plastic skin, no over-smoothed textures
