Prompt
A real photograph in red-carpet press-portraiture genre, 105mm lens at f/4 on a clean digital sensor, moderate depth of field holding the subject and the graphic ground behind in joint readability. A direct frontal flash is the dominant light: compact and near-axis, laying bright specular modelling down the front of the subject and pressing a subdued, soft-edged shadow close behind onto a matte step-and-repeat ground of repeated pale graphic marks. The finish is crisp and neutral with slightly cool whites, tight low-noise rendering, and every repeated mark on the ground even, legible and believably floored. A row of adult fans wears flag face paint with starry blue cheeks and stripe foreheads, cheering with hands high. Jerseys stay plain with no logos and an oversized foam hand waves in front. No lettering.
Light: controlled flash portrait light; palette of paint blue, skin warm and stripe red; loud, proud, fun.
Wide 16:9 frame. The standard flag shows exactly thirteen horizontal stripes starting and ending with red and a blue canton with star rows in the upper hoist corner; any interpretive flag stays recognisable and is never torn, burned, defaced or on the ground. No readable text, lettering, slogans or logos anywhere; any people are fictional fully clothed adults with clearly adult proportions and faces.
