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 mid 40s, lean face, a short tidy beard with a grey streak at the chin. Deep-navy field jacket — ordinary outdoor workwear, NOT a costume — with a faint smudge of blue-green bioluminescent sap glowing softly along the collar edge and a slim tool-holster strap crossing one shoulder. Bioluminescent street-tree keeper. Photorealistic portrait
