Affiche Séparée Photo et Schéma Rétro

Create an independently designed premium poster based on the reference photo, arranged in a vertical 3:4 composition strictly divided 1:1, each section occupying exactly 50% of the total height. Upper Half: Preserve the reference photo, maintaining the subject's identity, structure, pose, realistic texture, natural lighting, and original color atmosphere. Apply subtle, refined color grading with the visual quality of an art magazine or exhibition print. The surrounding background may naturally extend to fill the 3:4 frame without stretching or distorting the subject. Lower Half: Extract the primary subject, silhouette, structure, pose, and narrative relationship from the photo and reconstruct it in the style of mid-century vernacular graphic illustration, schematic line drawing, and two-color spot printing. Do not trace the photo. Use diagrammatic abstraction to compress complex objects into minimal geometric shapes, functional outlines, and essential structural elements, reminiscent of a vintage instruction manual, technical diagram, or vernacular ad print. Use direct black pen linework, flat diagrammatic perspective, economy of line, intentional whitespace, and a clear visual hierarchy with one primary subject explaining the narrative clearly.
