Prompt Content

Copy and paste directly into your model or internal evaluation tool.

Use the attached photo as an identity reference only. Keep the person's recognizable facial structure, eye shape, nose, lips, jawline, skin tone, hairline and hair characteristics, and their apparent adult age. Do not copy the clothing, background, pose or lighting from the reference. A night photograph of a {argument name="setting" default="city square"}. The flat side wall of a {argument name="building type" default="six storey brick building"} fills most of the frame. A projector on a rooftop opposite throws an enormous portrait of the adult woman onto that wall: head and shoulders, roughly four storeys tall, three quarter view, calm expression, eyes looking slightly down and to the left as if she is watching the square below. The projected portrait behaves like light on brick, not like a printed poster. It dims and warps where it crosses window recesses, a drainpipe and a fire escape. It breaks and skips across the mortar lines. Its edges fall off softly at the corners of the wall. There is a slight keystone distortion because the projector is not level with the wall. Down on the pavement at the bottom of the frame, small, the same adult woman stands with her back three quarters to the camera, hands in the pockets of a {argument name="outfit" default="long dark coat"}, head tilted up, looking at her own projected face. She is about one fifteenth the height of the projected head. Environment: wet paving stones, a bicycle chained to a post, a closed kiosk, one other pedestrian walking out of frame, a bus stop sign, the glow of a street lamp. Camera: standing on the pavement about twenty five metres back, phone at chest height tilted slightly up, vertical 9:16 frame, the building filling the top three quarters and the small figure placed low and left of centre. Light: the projector is the brightest thing in the scene. Cold street lamps and a red traffic signal reflecting in the wet stone. Her small figure is lit only by projector spill and street lamp, so her face is barely readable and that is correct. Realism: dust and haze visible in the projector beam high above, brick texture showing through the projected image, slight flicker banding, a soft blue night sky with no stars, grain in the shadows. The projection must read as light thrown onto a rough wall, not as a poster stuck to it. The large projected face must clearly be the same person as the small figure below. Do not add a second projected image. Do not clean the wall.
