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 40s, dust ground into the creases of his face, a magnifier loupe folded against his temple on a slim headband. Sand-coloured excavation layer with reinforced shoulder panels and a small sample vial holder at the collar. Anthropocene strata excavator. Photorealistic portrait
