A passport-style ID photograph of a person. The photograph itself fills the entire frame edge to edge — not a document, not a card, no text, no borders. STRICT FRAMING: crop ends at the middle of the upper arm, nothing below the armpit in frame. Straight on at exact eye level, centred, looking into the lens, calm neutral expression. BACKGROUND: completely FLAT uniform pale mint-green, one even tone, NO gradient, NO shadow. Flat frontal lighting. The subject: a Korean man in his 50s, heavily weathered face, a thin filter-mask scar line beside his nose. A practical charcoal work jacket — ordinary industrial workwear with a discreet slim intake vent at the chest and a subtle powered shoulder seam. NOT armour, NOT a military exosuit. Atmospheric carbon capture tower technician. Photorealistic portrait
