### Full prompt
```text
A premium gallery exhibition poster based on the reference photo of [a cultural landmark or architectural subject], formatted in a 3:4 vertical layout strictly divided into two equal 50% halves.

Upper half:
- Preserves the realistic photograph from the reference photo, retaining accurate subject structure, natural lighting, shadow depth, and authentic textures.
- Subtle, refined editorial color grading suited for an art book or museum catalog.
- Natural extension of background scenery to fit the frame without distorting or stretching the primary subject.

Lower half:
- A modern graphic deconstruction combining antique rubbing prints, folk monograph catalogs, and Swiss modernist poster design.
- Extracts the core silhouette, key posture, and symbolic essence of the subject from the upper photo into a single focal graphic motif with minimal narrative accents.
- Built on a rigorous geometric grid (circles, arcs, intersecting axes, and proportional ratios derived from the subject).
- Utilizes negative space, silhouette play, and subtle typography placeholders aligned along geometric tangencies.
- Color palette: textured light paper background, one deep dark structural color, and one or two accent tones sampled directly from the photograph above, featuring subtle risograph and stone-rubbing ink textures.
