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 woman in her late 30s, hair tied back, a delicate array of tiny contact microphones clipped along the outer edge of one ear. Deep indigo research top with a woven waveform pattern subtly raised across the shoulder. Cetacean language researcher. Photorealistic portrait
